MyBB Community Forums

Hello, Ive just installed a forum & although am able to log into the admin panel, I cant log into the forum.
Ive tried changing my password in the admin panel & recieve the following error 'The language you selected does not exist. Please select an existing language.'

I created another user account & logged in with that. It showed me the 'you have successfully logged in' screen & then took me back to the forum index where I was still not logged in.

Any ideas what the problem could be?
Thanks

Cookie setting are wrong. What is the URL of your forums.

And select a language that isn't 'Default' to stop the language error.

Okie thanks, I managed to sort that problem.
The final problem I have is when I click 'portal' I get this error message
MyBB has experienced an internal SQL error and cannot continue.

This is the second time Ive installed this forum today & still the same error when I click portal link on front page
Any ideas anyone?
Thanks
