MyBB Community Forums

So I recently installed MyBB on a forum I was going to be working on, and I thought that before I devote a ton of time into it, I should make a test post. After clicking on "New Thread," and clicking post, I was sent to an error page.

Links removed - problem solved

Edit: Reinstalled MyBB because of small mistake on my end. Error still occurs though.

Reupload ./inc/functions_post.php.

Oh, I was reuploading showthread.php this whole time. Thanks, Nathan! Works perfectly
