CMS Made Simple Forums

Help!
Since I activated pretty URLs, my FEUs can't get into the website. Once they log in, nothing happens, they are still prompted for user/password. Authentication works fine, as if they try to login once more, they get an error saying user is already logged in and in admin panel you can see them logged in!

cleared cache and all cookies form browser?
logout out in admin panel?

then try again...

what version of CMSMS, FEU, CC?

what does your template code look like for protected content?

For now, I deactivated pretty urls because this issue was just too big.
The main reason for using them was for our News RSS feed, but I found out it works just as well with index.php?page=feeds/news

Everything is up to date.
