I get an extremely annoying error when using Opera 9.5...whenever I click on "reply" on a thread, I am asked to log in, even though it shows me as logged in in the upper right. I enter my login information, it thanks me for logging in, and it redirects me to the login page again, asking me to enter the info again. I can navigate away to pages like this and it shows me as logged in, but it will still ask me to log in when i click reply. AFAIK from my experimenting, it only occurs on Opera, so I'm sure its a problem there.
yes, im a member at e46fanatics and i think its vbulletin. i had no idea there would be any correlation. the weird thing is i couldn't replicate it in firefox or chrome
