Hello @circoleto2022
I’d be glad to help you get this sorted.
I found another report of this same error and would like to check if the following workaround fixes the error you are seeing:
1) Deactivate Facebook for WooCommerce under Plugins > All Plugins
2) Navigate to your WordPress options page https://yoursite/wp-admin/options.php (be sure to have a backup of the site, and only edit the following fields) -In here please clear the value for the following fields:
wc_facebook_external_business_id
?wc_facebook_system_user_id?
wc_facebook_business_manager_id?
wc_facebook_merchant_access_token
?wc_facebook_page_access_token?
wc_facebook_page_id?
wc_facebook_pixel_id?
If it does not show these fields, or if the fields are blank, that will be fine.
3) Once that’s done, please re-activate Facebook for WooCommerce extension under Plugins > All Plugins and then click Get Started to re-connect to your Facebook Business Manager, select the same assets for Facebook Page, Pixel, and Catalog.
This should ‘reset’ Facebook completely, and allow the Pixel to be re-engaged as well as the Business Manager. As long as there is a non-conflicting catalog (see #1 above) then it should connect.
Please let us know the results.
