Once I added different subscription plans to our Membership plugin we get a header error when testing the sign up form.
We get three lines of errors like this:
Warning: Cannot modify header information – headers already sent by (output started at /home/xxxx/public_html/wp/wp-includes/general-template.php:1682) in /home/xxxx/public_html/wp/wp-includes/pluggable.php on line 680
(681 & 682 are the other ones)
We didn’t have any problems setting up test accounts before it just started after we setup subscription plans. It also only happens when someone is trying to sign up and register an account. If we login to a test account and click on one of the plans then the header error doesn’t show. It’s just when we go to the subscription page. Click which subscription plan we want, then create our account. The page after that is the one that will take a user to PayPal and that is the page we get the header errors on.
Do you have any idea what is causing this? Like I said, we didn’t have any problems before we setup subscription plans.
Please let us know as soon as you can. Thanks.
