Do you use templates from them? Do you get the "URL Error (32767): An error has occured while trying to browse through the proxy. Failed to connect to the specified host. Possible problems are that the server was not found, the connection timed out, or the connection refused by the host. Try connecting again and check if the address is correct." when trying to use ur own proxy? How do you fix this?
this sounds like the php is trying to contact a database and you have not setup a database or have not configured the config.php file correctly to contact the database. make sure you have done everything to set it up correctly.
I use it without any problem.. Try look into your proxy code to see what's wrong... or my best suggestion is to find another template..
