In simple terms, Incapsula is a multi-function CDN service, initially designed to boost the website’s workflow, filter malicious traffic, block everything from DDoS assaults to spamming attempts to more sophisticated database injection attacks, provide load balancing and preserve the web page against known and emerging threats, including SQL injections, remote file injections, cross-site scripting and more.
Incapsula is a well-known and frequently used tool in the world of CDN. By means of its enterprise-level security measures, this service will obstruct the migration, so you’ll have to disable it. For this purpose, contact your hosting provider or do it manually, if the web store is hosted on your own server. To turn Incapsula off, follow step-by-step instruction listed below:
- Log in with your Incapsula account and open your admin panel;
- Check out the Incapsula status of your website (Fully Configured, Partially Configured, Not Configured);
- Click More button;
- Click Disable to set the status to Not Configured;
- Now, your Incapsula service is turned off, enable it when the switch is successfully finished.
Though we’ve already found solutions to all common issues that might occur during migration procedure, and implemented them, sometimes a rare mistake can appear, caused by peculiar file types or file coding, absence or presence of certain extensions etc.
If this kind of error pops up during the transfer, it’s best to contact our Support Team right away. Having both of your stores at hand, we’ll surely fix the problem.
We guarantee that after running a troubleshoot once, the issue will be resolved for good.
Yes, data can be migrated from stores installed on WordPress Multisite, but only in terms of Data Migration Service Package which includes assistance of Cart2Cart tech team.
Due to technical restrictions, however, such transfer won’t be available via automated migration.
Please contact our 24/7 support for more info.
This usually means that connection to your server can’t be established properly, or Cart2Cart’s Connection Bridge (file needed for data exchange) can’t reach your store’s database.
To fix the issue try the following:
- Double-check if the links to your store on Migration Wizard are valid.
- Upload Connection Bridge manually - download, unzip the files and paste them to your store’s root folder via FTP.
If that doesn’t help, contact our Support Team - we’ll gladly help you find a solution.(more…)
The common reason of internal server error are incorrect permissions for bridge folder.
- Specify the file permissions 755 for bridge2cart directory.
- Specify the permissions 644 for bridge.php and config.php files in bridge2cart directory.
- If it doesn’t help, contact your system administrator who can provide you with server logs access for further error detection. Or request for technical help from your hosting provider.
The reasons for the error may be the following:
- Incorrect access details to server database are specified in configuration file. Contact your system administrator to get the correct access.
- There are no read permissions for configuration file. Provide read permissions for the file or contact your system administrator.
It seems that Security Token of your account and Security Token of Connection Bridge downloaded to your website doesn't match each other. It could happen if Bridge was downloaded from another account that is used for your migration. To resolve this issue do the following:
- Click ‘Continue Migration’ button on “My Migrations” page.
- Get to the 1st migration step and download the Connection Bridge one more time. Unzip it and paste to the store's root directory.
- After re-uploading the Bridge, proceed with your data transfer.
To setup connection to your store data Cart2Cart creates test queries to your database. If your database responses are not correct, the message “MySQL Response Error” will appear. It means that we have got connection to your store, but something went wrong while reading the responses. The best way to solve the problem is to submit a ticket to our Support Team.(more…)
Cart2Cart Service is designed for typical shopping cart structures. You may be not able to perform an automated migration, if your platform differs from the default one (deep customization including changing the database structure). However, our tech engineers will transfer all your data, if you purchase one of Data Migration Service Packages.(more…)

Cart2Cart provides a possibility to map your customer groups from Source cart with those that will be displayed on Target cart. Pay attention, that Customer Groups need to be already created on your Target Store, in order to map them during the migration. If you don’t have Customer Groups created on Target cart, here you can see how to do that.
To create customer groups in Magento you have to go to Customers -> Customer Groups and click Add New Customer Group in the top right of the page.
Then fill in the "Group Name" and select a "Tax Class" from the dropdown
- Group Name - You have to enter the name of the Customer Group as if will appear throughout the admin.
- Tax Class - Each Customer Group will be assigned to a Customer Class Tax. Tax classes will not be assigned directly to customers, but rather to Customer Groups, which are then assigned directly to customers.
After that simply click “Save Customer Group”.
To create Customer Groups on PrestaShop, navigate to Customers -> Groups . There you will see 3 default Customer Groups - Visitor, Guest and Customer. To create a new one click "Add New" and fill in a form.
- Name - how your Customer Group is going to be called. It is recommended to use short and descriptive name.
- Discount - a discount that will be applied to members of the group. it will be applied to all products on your shop.
- Price display method - here you can include or exclude a tax.
- Show prices - decide if you want customers to see the prices.
To create a new Customer Group on OpenCart, go to the Sales -> Customers -> Customer Groups page . Above the list, click the "Insert" button. There you will have to provide Customer Group Name, Description, approve or disapprove customers logins into their store account, allow the customer to select their company no. or Tax ID.(more…)
Possible reasons for the error are:
- Bridge is located in the wrong directory. It should be located in the root directory of your store.
- Configuration file is missing or its location is incorrect. The error may also occur if the configuration file was renamed.
- The cart is not supported. Bridge is installed correctly, however the shopping cart is not identified by the service and so configuration file cannot be found. Check if your shopping cart is in supported carts list.
- Configuration file is not readable. Provide read permissions for the file or contact your system administrator.
The request for the server is too large.
- Increase the value of parameters memory_limit and post_max_size in PHP configuration.
- If the module suhosin for PHP is installed on the server, increase parameter suhosin.post.max_value_length. Usually, the value of 32 Mb is enough.
Possible solutions for the issue are:
- Check if bridge location is correct. It should be located in the root directory of your store.
- Check if store URL was provided correctly.
- If the above issues are not causing error, you should check .htaccess file which is located in the root directory of your store. Make sure there are no redirects or other directives which can block access to the bridge. For Pinnacle Cart you should add exception for bridge in .htaccess file. With this aim change the line:
- You may contact your system administrator for detailed instructions.
into this one:
Access to certain files or folders is limited.
- Check the access permissions. For bridge2cart folder specify the file permissions 755. For files in the folder specify permissions 644.
- Contact your system administrator to find out if there are no access restrictions for bridge file. Usually, restrictions are specified in .htaccess file.
- The main page file of your site should be called index.shtml, index.html, index.htm, index.phtml or index.php. Use only lowercase characters (files index.html and Index.html - are two completely different files).To resolve error, upload an index page to your html directory. If you already have a home page called something else - home.html for example - you have a couple of options:
- Rename your home page to index.shtml, index.html, index.htm, index.phtml or index.php.
- Set up a redirect on the index page to your real home page.
- Set a different default home page in your .htaccess file.
- A 403 Forbidden error can also be caused by incorrect ownership or permissions on your web content files and folders.
If you have such error, try the following solutions:
- Make sure that access to shopping cart content is not blocked with HTTP Basic Authentication. HTTP Basic Authentication is a protection method which requests additional login and password to access webpage or other resource.
- Check if your store content is available online during migration performance.
Please, make sure you have uploaded a Connection Bridge to your store root directory. You can check if the Connection Bridge files have been installed correctly. To do that enter http://[yourstore url]/bridge2cart/bridge.php within your browser address line. If the message “BRIDGE_INSTALLED” appears, it means the bridge files are working correctly. Otherwise set the permissions as following:
- "bridge.php" - 644 (if /bridge2cart folder permission is set to 755) or 666 (if /bridge2cart folder permission is set to 777), depending on your server configuration;
- "/bridge2cart" folder - 755 (if bridge.php permission is set to 644) or 777 (if bridge.php permission is set to 666), depending on your server configuration.
If you face some troubles while setting the permissions, please contact our Support Team.(more…)
Please, create image directory and set the write permissions (chmod 777) to it and to ALL subfolders/files it contains.
The reasons for the error can be the following:
- Path to image directory doesn’t exist. Create image directory.
- Path to image directory doesn’t correspond to the path specified in store configuration.
- There is no access permissions required. Set the write permissions (chmod -R 777 [images_dir]) to images directory and to ALL subfolders/files it contains.
- The shopping cart may use non-default image directory. In this case contact Support Center of your shopping platform.
- If Target store is Magento fresh install, create folders catalog/category and catalog/product in the folder media.
In the case of such issue you should check the language configuration on your store. The shopping cart must have at least one language used by default.(more…)
If you cannot connect to host, pay attention to the following points:
- Check if store is available online at the moment.
- The firewall may block certain IP requests. For more details on the issue contact your system administrator or hosting provider Support.
Web browsers request for information from the server, and when it is performed, it sends an Accept header. In case if the server is not able to send that data in the requested format in the Accept header, then the server sends the 406 Not Acceptable error.
The 406 error can appear accordingly to your mod_security rule on the server. Mod_security is a security module of Apache web server, usually permitted automatically on all hosting profiles. In case if a site, page or even function violates one of the rules, server can send the 406 error.
How to Prevent
You can turn mod_security off. Also, there is a possibility to disable a specific rule or each domain individually. Thus, if you wish to disable mod_security, go to mod_security using modsec manager plugin in control panel.
Note: There may not be the option of turning mod_security on/off in your cPanel or dedicated servers. In such cases, use command line using SSH or contact tech support to enable/disable this option.
If you have any questions, contact Cart2Cart Support Team and get all the answers in no time.(more…)
