Envato Market 2 not working

Thanks. My site is on sister company of Hostgator called Site5. I have WHM access and have added IP to the allowed IPs on my firewall but made not differences.

This is just my development server and don’t want to use for main server when I go live. Will move to a dedictaed server for that with deifferent domain name. But need to get site working and signed off before I do that and at this rate I can’t see when that will happen. This is a blocking issue for me at the moment.

regards

David
