hi. I just encountered a really weird problem. I was just browsing through some pages in admin cp and now most of everything in the forum seem to be disfunctioning. I just browsed through "Skins & Templates-> HTML Templates-> Manage HTML ->expand to edit" for a few categories, looking for something trivial but I didn't touch or tried to edit a single damn thing. I can't explain how and why things messed up. I cannot open subforums (I can open them from links through last post links etc though), add reply and some other options have disappeared, or don't work, i can't create threads etc. anyone know how and/or why this happened and how to fix it? =/ thanks for any help in advance
