vBulletin 3.8 Login Problem with IE - This is strange
 

Hi* new to VB and I noticed a login issue which is a really strange problem. When I login it says it's redirecting and logging in as it should* then it directs me back to the /forum index page not logged in.

- Login seems to only be an issue with IE. Firefox seems to work.

- Clicking "Remember Me" allows the login to work.

- http://mydomain.com/forum will allow me to login* however http://www.mydomain.com/forum does not allow me to login.

Don't know if it matters* but the forum is in sub /forum.
