UBB.threads PHP Forum Software Community Forums UBB.threads 7 Bug Reports Fixed Bugs "Automatically returning to forum" not working

After editing a post the message "The thread has been modified. In a moment you will be automatically be returned to the forum" comes up.

Since our admin upgraded to 7.5.8 from 7.5.6 (I think it was) it does not return you to the forum. Is there a setting he missed or something.
