Hey there. Every time I log into my Vanilla Forums on my server, I get logged out for some reason. It won't let me retain the log after a page redirect either.
Make sure the user you're logging in as has a role and that that role has sign in permission.
Weird thing is though, it won't let me back into the dashboard to see if that is set...
Try clearing your cookies.
Still nothing. I managed to also log into the dashboard via the login page for that. I'm set as an administrator though. I think there may be a bug on the main discussion page, because I can only retain a log in by going to /entry/signin?Target=dashboard%2Fsettings and even after that on the profile pages, I can't edit them becuase I get logged out...
Is the Cookie Domain set properly in your config file? It should be either and empty string '', your full forum hostname 'whatever.mysite.com',
or your top level domain with a period in front '.mysite.com'
