Thanks for sharing the additional information that you have no connection with the domain.

Can you navigate to https://YOURSITE.com/wp-admin/options.php and search for the field wc_facebook_external_business_id.

If this is populated with some details such as store-name-98asihsaoihas can you please change the last string of characters (starting with “98” in my example) to another random combination of letters and numbers. Please then try reconnecting.`

NOW IT WORKS thank you so much guys!

I confirm I’m trying to connect with my own fb account and I’ve never heard about the [wrong domain]. Nothing in my fb account or facebook BM has ever been related to th [wrong domain]; also for fb page of the [wrong domain].
It seems like the fb plugin request starts from [wrong domain] and not my website.
Is there any db table I can check?
