I have a couple of users that are having problems loggin in. Mind you it is only a couple that I know of, doesn't make sense that it doesn't effect everyone.

They enter their information into the login block and it takes them to the "Thank you for loggin in xxx". Then when they come back to the page, it still has the login block, they aren't shown in the Who's Online and they don't have any permissions.

I read another post that sounded similar to this and they were having to login twice. I had them try that, but still no luck, everything the same.

I'm using version 2.0.9.2.

Likely a problem with those silly personal firewalls. Search this site for firewall or in the FAQ and you'll find lots of answers.
