Hi there, I was on with chat support earlier but didn't get very far, except for try disabling plugins. However, everything was working before I mapped a custom domain to the site, so I know it's not that.
My issue is when you go to My Sites > Network Admin > and then any of those links, like 'Sites', 'Dashboard' etc. I get re-directed to the login page and then it loops and doesn't log in. All sub-site dashboards and links work perfectly, just the network admin which does not.
The URL it is supposed to go to is like this:
However it re-directs to here:
I have this in my wp-config:
define( 'WP_MEMORY_LIMIT', '512M' );
define('COOKIE_DOMAIN', $_SERVER['HTTP_HOST'] );
*That last line added by WPMU Dev which fixed the sub-sites admins not working, but now those are great.
Extra information which will hopefully help; this is my Cloudflare and Cloudways domain setup:
When in my back-end, I am at this URL:
However when I hover over the network admin links, I see it pointing to this URL: http://jwbeauty.net/wp-admin/network/sites.php
I noticed there's no 'www' there. Not sure if that has anything to do with it, but just want to point it out.
I have enabled the support access in my back-end. Any help is much appreciated. Thank you.
