Dear Mousavi,

I'm not sure if posting this helps, since you can't read any answers, but I might as well try.

I assume that you got an e-mail from the forum (/me) that there was a new reply. You clicked the link, which brought you to the disucssion you started. Now you can't see any answers, is that correct?
What do you see?

I have tested it with Firefox and Internet Explorer and for me it works. If you can provide more details we might be able to track down and solve the issue.
I recently upgraded the forum so that might have caused some problems (f.i. the edit box width is not correct... Update: changed to another plug-in which works better.).
