Has anyone out there come across this problem before.
Why would wp-cron.php be trying to go to https://mysite.com when the whole site is running on https://mysite.com.
I done a db search for any record of https://mysite.com and not found anything. I have added
define('WP_HOME', 'https://mysite.com');
define('WP_SITEURL', 'https://mysite.com');
to my config file and this has not made a change.
