what did you update? Only ATS or Akeeba Backup, too?

Because in the ticket you're talking about ATS, but the error message refers to Akeeba Backup, too.

If I recall correctly I updated either Akeeba Admin Tools or Akeeba Backup before trying to update ATS.
The other ones updated fine, error message only on ATS.

Please unpublish the following plugins:

  • Installer - Admin Tools Professional 
  • Installer - Akeeba Backup Professional
  • Installer - Akeeba Ticket System Professional

Then try installing the new versions of our extensions which had previously failed. It should now work.

Please let me know if that works for you.
