Hi, I try to use the API for Sitebuilder 4.2. When I try to create account, use ServiceFacde/4.1/accountWebService.asmx?op=CreateAccount I get the http 500 Error. Can you tell me what step should I do to make sure this API work fine? I need to use this API because I want to integate this Site builder with my control panel. Please kindly give me some instruction, so I can use this API. Thanks. Best Regards, Junaidy.
