Troubleshooting

Nothing works after the search/replace operation!

It's time to use your backups!

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.
