I get a popup saying there was an AJAX error
This happens occasionally and could be for a couple of reasons:
When the script starts, it attempts to start your WordPress or Drupal installation to auto-detect your username and password settings. If this fails, you will see a message informing you that auto-detection failed. You will have to enter your details manually.
Script was unable to set the timeout so PHP closed the connection before the table could be processed, this can happen on some server configurations.
