I have an ssl on webuypinball.com. My API credentials from PayPal are installed correctly. Yet I keep getting a "Security header is not valid" when trying to join.
This site is NOT the main domain name. It resides in a sub directory. Getting the ssl to verify took an extra step (and an extra week). Could that folder be tripping me up here as well?
Any help on this topic will be a great help!
If you are an arcade game collector and fix this issue I will give you free access for a year as a THANK YOU! Google "Sell arcade game" or "Sell Pinball Machine". Lets just say I get lots of hits.
