Is there any support for this?? It seems the developers dont care so much. This is a major problem and does not allow me to try out the plugin before considering to buy the gold cart. I guess i will not get the opportunity.
I installed this today on WP version 3.1.2 and i have had exactly the same problem.
Following your advice on removing the ‘Product Page’ stuff and all is ok now with the plugin deactivated.
So how can i use this plugin without it destroying my site? Very disconcerting :/
