What I am seeing is unusual - after creating an account & logging off
Returning to you home page and selecting login - entering my login info and clicking login I am redirected to a page

/index.php?main_page=login/index.php?main_page=login&action=process

"&action=process" is what is not normal

Do you have any account addons installed?

[joyofwicca]

no add on's im confused too ..

Try switching to the classic template and see if there is a difference
This would limit your searching to the template files

[joyofwicca]

no difference on the switch

Well then please provide your server information

New install or upgraded - from what ver to what ver
