XF 1.5 Significant Problem with v1.5.3

    I recently just installed (upgraded) to the v1.5.3 maintenance release and one on my members tried to post with the link in it below and all hell broke loose.


    For whatever reason the below pops up and it's caused a significant problem. I've had Auto Link Rebuild installed for some time and when I went into tools and tried to run it the same type of error happens and it screws everything up and gets caught in an unfinished task state. Even if I restore My SQL from a backup and uninstall that add-on the same thing happens again when I try to make a post with the same link.

    Anyway, how to correct this?

    You have a BB code media site that isn't defined properly -- it's defined as a regex, but it's not valid. Unfortunately, the error doesn't make it clear which one, but if you have any add-ons that deal with BB code media sites, I would look at any one they have changed. (Or any ones you've added or customized.)

    It turned out to be something in S9e. I'll let the guy know when I have the chance.
