I start my session in my index.php5 file, so I am wondering if the keeping the session set has something to do with my MCV? Any ideas?
I load my login script with the following URL: http://www.example.com/index.php5?module=authentication&action=newAuth
Thanks again for all the help!
My index.php5 file
