Non-s2member PayPal buttons error

Hi,

I had PayPal buttons working fine on the WarriorForum site.

However, I’ve now implemented a new membership site using s2member and have defined PayPal button on the site. These are working fine.

However, when people purchase using the PayPal buttons on the WarriorForum they are getting an error message. Their payment still goes through and I receive funds but, it’s a little disconcerting that the PayPal buttons are now giving an error message.

Also, the error is coming from my membership site, which has nothing to do with the WarriorForum PayPal buttons.

This is the message:

ERROR: Unable to verify $_SERVER[“HTTP_HOST”].
Please contact Support for assistance.

If you are the site owner, please check the custom value in your Button Code. It MUST start with your domain name.

If you have experienced this problem I’d really appreciate knowing how to fix it.

Thanks
Robert
