When restoring a package to a target site – the import / restore stops with this runtime error:

Unable to rename tables, please check that your database is not empty or these tables exists


Based on previous cases – this is usually caused by some customized database configuration in your source site. It creates an incorrect database / incompatible dump to your target database. As a result – you will get this error when doing an import.


The most recommended solution is to re-create the export package using the latest version of the Prime Mover plugin. This will ensure the exported package is correct and includes the fix to handle this error.

In detailed steps:

  • In your source site (where you create the package) – make sure you are using the latest Prime Mover version. As of June 2024 – this should be Prime Mover 1.9.9 + / Prime Mover PRO 1.9.9 +. If you are using an old version – deactivate and uninstall/delete the version. Please download the latest version from the repository (for FREE version users) or inside your Freemius account for PRO / Trial users.
  • Now you are using the latest version of Prime Mover, re-generate the export to your target site. If you are using PRO version – don’t check the encryption setting in the export. This will disable encryption for the package which will make troubleshooting easier later on.
  • In your target site (where you want to restore the package) – make sure also that you are using the same latest version of the Prime Mover plugin.
  • Finally, restore the package and you should not see this error.
