Whitelisting and Access Token Issue for Facebook

Hello,

So I’ve been using the plugin on two of our websites (babyprepping.com and babycaremag.com) and both have been unable to post their scheduled posts on our Facebook social media. I’ve checked the logs and found the following issues:

– For BP, it says that “The remote check can not access your website. You need to whitelist this ip 107.170.26.57 in order for the schedule to work properly.”

– For BCM, it also has the whitelisting issue, plus this additional message: “Error validating access token: The Session has been invalidated because the user changed their password or Facebook has changed the session for security reasons.”

How can I whitelist the IP and fix the token validation issue so that our sites are able to post scheduled posts on Facebook again?

I’ve provided the system reports for both sites below:

Thank you,
