Fixing common Connector Setup errors

Getting 403, 404, or 406 errors with mp_connector? Step-by-step fixes for Apache and Nginx servers resolve connector setup issues fast.

When setting up the connector for your web store, you might encounter some common issues that could prevent it from working properly. Don't worry; we're here to help you troubleshoot and get things running smoothly! Below, we've outlined some easy-to-follow steps to resolve the most common connector installation problems.


Problem 1: 406 Not Acceptable

The "406 Not Acceptable" error occurs when a request sent to your source store server is blocked by the server. It often happens due to server settings, such as mod_security limits on POST requests. Follow these steps to fix it:

1. Increase the POST request limit on your server. For example, set: post_max_size = 512M


2. Check server security settings, such as mod_security ensuring they are not blocking the request.

Problem 2: 404 Not Found Error

If you're seeing a "404 Not Found" error when searching for the connector, the connector likely wasn't installed in the right location. Follow these steps to fix it:

1. Make sure the connector is in the correct path: Your connector should be located at your_store.com/mp_connector/connector.php. Double-check the path to ensure it's correct.

Problem 3: 403 Forbidden Error

A 403 Forbidden error means your server is blocking access to the mp_connector. This is most commonly caused by restrictive Apache configuration, either in the .htaccess file or directory settings.

Important Notes

  • Always create a backup before modifying server configuration files.

  • Some hosting providers restrict access to server configs. If you cannot edit them, contact your hosting support.

  • After making changes, clear the server cache or CDN cache if enabled.
