There was a problem with the AJAX request…
There was a problem with the AJAX request, we were expecting a serialized response, instead we received: <data>
There are generally only three scenarios where this error occurs:
- PHP errors or notices are included in the POST response. Please check these error messages and either fix or suppress these notices accordingly.
- The remote plugin is out of date, please ensure both the local and remote websites are running the latest version of WP Migrate DB Pro.
- There is custom code on the remote that redirects away from admin-ajax.php very early in the admin request flow (e.g. admin_init hook).
