Install Issue

Hi, I bought the pro version and installed it. After providing all information (application ID etc) I got the following error message during the autorization step 3: Given URL is not allowed by the Application configuration.: One or more of the given URLs is not allowed by the App’s settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App’s domains.

WHat do I have to do in order to get the plugin running?

Many thanks!
Carmen
