Integrity constant violaltion after upgrading to Froxlor 0.10.17 in General Discussion Posted May 16 · Report reply 44 minutes ago, d00p said: That's what I meant, you've clicked on finish the process and not "integrity check" which is on the admins left side menu Very weird though, as said the updater should've removed any duplicates prior to setting the unique key. I even added fake duplicates to my database to test that and it went through smoothly. I can't remember off the top of my head the screen immediately you login to finish the update.. I just remember clicking on the green button.. Anyway, yes it's weird that the update didn't remove those duplicates.. Just worth to mention that on another server the update went through without any problem. Thanks for everything!.
