Presumably something's been changed. I log in everyday, mainly for the forums but suddenly yesterday, the latest posts section disappeared. Not only that, I tried every link possible to get to the forums and every one of them ended up with a page address of http://forums.mmorpg.com/sso
that never loads.. Eventually, I decided to try manually removing the sso bit and the forums appeared again.
I'm using Firefox, have AdBlock plus installed but mmorpg.com is whitelisted and normally works perfectly.
Please change whatever you did to repair the links thanks.
