Thanks for that; I see the issue now when I log into the affiliate customer's account and click on the link for the referrer_main page.
The as-shipped version of SNAP Affiliates does a redirect from referrer_main to the *login *page if a customer's not yet logged in. Your template's rendering of the referrer_main page is what's displaying that "Please login to access your referral statistics".
Check the file /includes/templates/tc/templates/tpl_referrer_main_default.php and compare it to the as-shipped version of that template, which should be in /includes/templates/template_default/templates/tpl_referrer_main_default.php.
The problem is that my affiliates are logging in to their account, then they go to their affiliates page, which is absolutely fine. The issue arises, per my private message to you, when they try to go to their payments page. They are sent into an endless loop of being requested to log in when they go to the payments page, and no matter how many times they try to log in, they are sent back to that request for login when they try to go to the payments page.
