Why did this happen..

At my forum, when u go to New Thread, Reply to Post, or anything having to do with posting, after u press post, it goes to a database error. I have recently installed some hacks, but what is this cause of this? The post shows up in the forum, but when u press post it brings u to database error and not return u to the site, you must go back manually. Help appreciated, thx.
