If you receive a notification stating the following:
We cant seem to find your Bridge File, due to this we have deactivated your channel.
This means that we attempted to access the bridge file on your website located at /bridge2cart/bridge.php but we were greeted with a "404 Not Found" error. This would usually be due to the bridge file being removed on your store, so to fix this you need to re-add the bridge file to your store and re-activate the connection.
In some cases, a .htaccess file or firewall could be redirecting legitimate requests to a "404 Not Found" page so double check your .htaccess and also ensure you have our IP address whitelisted: 188.8.131.52.
