Hey @mahmoudmagdy
Thanks for contacting us about Facebook for WooCommerce! I am happy to help out ??
We have a snippet that will give us some additional error information, which may give us a better indication as to what might be happening here. Can you please add the following snippet to your site and attempt to connect to Facebook again? If you aren’t familiar with adding custom code to your site, here is some information as to how to do it. Personally, I like the free Code Snippets plugin method.
You can view the snippet here:
add_filter( 'wc_facebook_connection_proxy_url', function() { return 'https://wc-connect-test.skyverge.com/auth/facebook/';} );
Once the snippet is in place and you have had a chance to try to connect to Facebook again, would you please send a screenshot or text of any additional error messages that show?
Cheers,
Steve
