Is that linked to my bug too guys? Sorry for posting this in the "FIXED" sub-section first.
I'm also getting an error after 7.5.7 but it means I can't re-edit longer posts with formatting after the initial post.
[deleted my pathname here]/ubbthreads/scripts/modifypost.inc.php
SQL Error: Incorrect key file for table '[deleted my pathname here] ubbt_POSTS.MYI'; try to repair it
SQL Error #: 126
