Hello, I searched for this issue and found a couple suggestions however they didn’t work for me. I have 4 small personal websites using Cloudflare, 2 phpBB forums and 2 WordPress. ALL have logged-in problems. I can log in (as admin) but when I leave the site and return, I’m no longer logged in despite using the option of remaining logged in. I have to login every visit. All sites have been in existence for a year or longer and never had issues with this until recently being setup on Cloudflare. I’m using Page Rules as follows:
*example.com/adm/* - Cache Level: Bypass, Disable Apps, Disable Performance
*example.com/ucp.php* - Cache Level: Bypass, Disable Apps, Disable Performance
*example.com/wp-admin/* - Cache Level: Bypass, Disable Apps, Disable Performance
*example.com/* - Cache Level: Cache Everything, Edge Cache TTL: 2 hours
All my sites use Lets Encrypt SSL and all URLs have forwards (www and non-SSL) to
Any help on this would be greatly appreciated!
