(Error 1) when trying to set up API

I am trying to start using the plugin. When I click the button to login to facebook, and then choose what pages to allow, and continue, I go to a white page that says Error (1). This is the address of the page I get to. https://api.web-dorado.com/fb/?ffwd_code=EAAGgZARDXC3MBAMqkSZBKROvGCuVbQwAKMVkLY4kFbsG3Th1Mt0aFJrEvSMP5KHFBhC5SbCeZCAQUTZAWWtDrPwBha1O5SusCZCBr1ZBZBO6snfHSDZCEbJm1TOpD3R5ZCmR2uEEhl65rZCQMd1UPXGO7qC1AhY58Nu6nluTVTYOH5YwZDZD#_=_

I have tried clearing the cache. Is there perhaps something else I can try? Thank you.
