Facebook Integration Issue on My Website – Need Help!

Dear Developer,
I am facing an issue with Facebook integration on my website, Cat and Dog(https://catdoginfo.xyz/). The connection is not working properly, and I am unable to link my website with Facebook successfully. This may be due to API configuration, app permissions, or a plugin conflict.
Please check the Facebook API settings, app credentials, and any related errors in the console. Also, verify if any firewall, security settings, or third-party plugins are blocking the connection.
Let me know if you need further details. Your assistance is greatly appreciated!
