'Friend feed', if you have it in widgets tab on left side, if someone uses scode or html, it breaks the whole site, cramming it in a tiny column on the right side of the page. Ive had this error off and on for months, but today was the first time i figured out how to fix it (before it seemed to randomly come and go). Using google chrome but also happened in other browsers. it fixed as soon as I removed friend feed/ and or forum posts/replies from friend feed this time. Please if you could look into this, Im sure others have come across this error and its extremely hard to figure out what was causing it.

:/ Yep, it's because some topic titles are made extra fancy with brackets. Site doesn't read the brackets as plain text, it sees them as code and that breaks all the things.

[ ] { } these bois in topic titles probably break it

I've had an issue with my friend feed displaying oddly in my dashboard when a friend posted on a topic that had brackets aplenty in the title. Removed forum posts from feed and it was all good.
