Multilanguage site problme in facebook auth link not whitlisted

Hi @ahmedmzda

As I see the slug for the language also appears in the login page, so it is necessary to include all of these URLs under “Valid OAuth redirect URIs” of the App.

Unfortunately Nextend Social Login can not know all of these URLs for each language, it will only be able to show the current one.
According to your login URL I see you selected a page for “OAuth redirect uri proxy page”, so what you could try is adding the redirect uris to your Facebook App for both languages, probably:
https://udolearn.com/en/oauth-redirect-uri-proxy-page/?loginSocial=facebook
https://udolearn.com/ar/oauth-redirect-uri-proxy-page/?loginSocial=facebook

If the problem would still occur, please get in touch with us directly on:
https://nextendweb.com/contact-us/nextend-social-login-support/
since we will probably need an admin account to check the problem on Monday when we return to the office.

Best regards,
Laszlo.
