Tried to spoiler images and the thread expoded.

I'm consistently getting a 500 Internal Server Error when trying to edit a thread to add spoiler tags.

Could be something I broke, as I've never spoiled stuff before.

EDIT: I can access the thread from my profile, and the spoilers worked as intended, but when trying to access from the forums I get the error.

EDIT 2: It moved the post to general discussion instead of the correct board, managed to fix it, but that's still fucked.
