I have a user who is trying to pay for subscription by credit card in frontend. He clicks the Mastercard icon and then the site pauses and finally gives a redirect loop error. This is the text from the error:

The webpage at https://www,,site,,org/cb-login/pluginclass?plugin=cbpaidsubscriptions&cbpgacctno=1&cbppdtback=22449a6d0bdbb51833e8163086e0a724&cbpbasket=1037&cbpshopuser=44fbda32b6855320c7ff8c688fb69a65&result=payform has resulted in too many redirects. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, it is possibly a server configuration issue and not a problem with your computer.

I cleared cookies for this site with no luck. I turned on maximum error reporting and nothing seen. I also install nightly build for CBsubs and still nothing. This user expired in 2012 and is disabled in CB if that helps.

Thanks

changing to HTTP doesn't - the page refreshes into HTTPS y itself and then fails again. Sent a ticket. thanks
sorry, you mean to change the setting in the backend to HTTP. I did that and it does work. I didn't go through with sending the CC information but the page does load at least. How can I fix this? thanks

just a heads up that although this method works to fix the loop error, now my users are getting alerts that the transaction isa going through a non-secure page and they are complaining. When can we expect this and the hard-coded non-SSL payment icons to be fixed?

This is what I use in htaccess to force www

RewriteCond %{HTTP_HOST} ^site\.org$ [NC]
RewriteRule (.*) www.site.org/$1 [L,R=301]

I commented those out and still get same issue. Anything else you can think of?
