I have htaccess set up to redirect /wp-admin/ back to my site for security purposes, to log in there is a random string of characters a user needs to type in e.g. mysite.com/a83990034dfae4/. Per your FAQ item (below) is what I am doing something that would cause wp-cron to not work? If so, is there a workaround?
Is your site private (I.E. is it behind some kind of authentication, maintenance plugin, .htaccess) if so wp-cron won't work until you remove it, if you are and you temporarily remove the authentication, do backups start working?
Thanks for any help!
