I guess it turns out it was a cookie issue. Cleared browser data/cookies and it started working again.

This is the main error I am seeing:

mod_fcgid: stderr: PHP Warning: count(): Parameter must be an array or an object that implements Countable in /var/www/vhosts/mydomain.com/httpdocs/wp-content/plugins/wordpress-ping-optimizer/cbnet-ping-optimizer.php on line 533

Yes I am having the same issue and came here to report it, but I guess nothing is being done about this since it’s been months already.
