Re: problim with topic send and edit topic

What forum version do you have? What extensions do you have installed?

forum version is PunBB 1.3.4
iam installed video tag    VideoTag (New BBcode tag ([video]) to display embedded flash videos.)

So, the problem is obviously in this extension. Try to ask its author about the issue.
