UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? cannot create new gallery in the Forums

This was a bug in 7.5 where the column was only 3 characters in length when it should have been 4.

As for the error you're getting now, you should just be able to run this:

ALTER TABLE `ubb`.`ubbt_forums` MODIFY COLUMN `FORUM_SORT_DIR` VARCHAR(4)
