To fix the logout when going to the non http:// or whatever URL your cookie is set to, you do this:
- Login to vBulletin's admin panel
- Go to "vbulletin options" > "cookies and http header options"
- Scroll down to "cookie domain" and write: ".talkfreelance.com" within the custom setting input - note this should already be in the suggestion dropdown box above.
No more annoying cookie problems...
