Thread titles fix


Today, there was a bug which caused:
- All existing thread titles, posts, and PMs to stop showing up when you tried to read them.
- Any new posts/threads/PMs you tried to make would not save, and ended up saved as blank messages in the database.

Both are fixed - existing content now shows up, and new content will now save correctly.

Threads/posts created during the bug have been cleared. If you've posted anything today that showed up blank, you will need to repost it.

PMs created during the bug have been edited to me to be just a link to this thread.
If you got a PM that's nothing but a link to this thread, assume the sender tried to PM you something, but failed due to the bug, and you should reply to the PM, asking them to repeat the last message they sent you. Link them here if they're confused as to why.
