I have a Premium SEO Pack – Wordpress Plugin installed and with its Facebook planner, we are supposed to authorize app after providing the initial settings.
I have provided all the settings correctly. Provide app id, app secret, app domain, site url (through add platform), settings->advanced->enabled browser oAuth login, provided Valid oAuth redirect URI http://example.org/psp_seo_fb_oauth .
But still I get the "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." error.
Also its not on localhost, but production server.
