What does it mean? Symbols is the place of my forum!

Hi!

I am scary... because I log in a topic (or categorie) and this appears:
(but this is just private browser! (opera private window)

My forum: http://diariesfrpg.hungarianforum.com

Just me is this?

Have you try seeing if it happens in any other browser? Try deleting your cache. I see your forum perfectly.

I think this is a problem with private window on opera and there for it's just a Browser problem. I don't use opera my self i think it's crap and has lots of problems with plugin's

I see your forum 100% fine in IE 8, Firefox, and Google Chrome

OK, thank you!
Actually, the new Antivirus (Nod32) caused the problem. I don't know that why, because... wow... I installed the Antivirus on Sunday morning, and thereafter came this problem. I found a program, and uninstalled the Antivirus, thence the forum working perfectly!

So... this is solved!
