Try removing and re-adding your Facebook accounts. Sometimes Facebook invalidates tokens on their end.
I’ve just tried that. I get the message,
Server Error
‘The website encountered an error while retrieving https://www.facebook.com/dialog/oauth?…It may be down for maintenance or configured incorrectly
Sorry, I think I’ve got a different problem to the OP.

Thank you once again !!!! GREAT JOB !!!!
I have been getting so fed up with people finding answers and not coming back I thought I would come back on this one have taken 48hours to find an answer.
This happens i understand because of custom post types or custom category types and is likely because an instance of a category ID is empty.
I found changing:
echo get_category_parents($cat, TRUE, ‘ ‘ . $delimiter . ‘ ‘);
to
echo is_wp_error( $cat_parents = get_category_parents($cat, TRUE, ” . $delimiter . ”) ) ? ” : $cat_parents;
fixed all my issues with the “Catchable fatal error: Object of class WP_Error could not be converted to string”
