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. Provided 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.
website url is example.org , oauth redirect url is example.org/psp_seo_fb_oauth , example.org added in app domains , add platform->site url included example.org . So there's no subdomain
I have checked this facebook.com/help/community/question/?id=542958419109491 already
I would appreciate your help. Thank you!
