I haven't had a chance to upgrade yet, but I turned debug on and this is the message I am getting:

File: /.../post.php
Line: 321

PunBB reported: Unable to create topic

Database reported: MySQL server has gone away (Errno: 2006)

Recently, when I try to create a new topic or post a quick reply on my board, I get an error that says I can't do it.  Other users have posted new topics, and no one has said that quick reply isn't working for them, so I am just stumped on why this is happening to me.

Any thoughts on where to start with this problem?

Thanks

I am on 1.2.11
Maybe I should just upgrade first?
