I upgrade from vBulletin 4.3 to v5.7.2. PHP version is 7.4.2
Our website is https://www.datanumen.com and the vBulletin forums are installed at Forums - Data Recovery Forums . We enable Cloudflare Pro for the whole domain datanumen.com, so the forums subdirectory is also affected.
Before starting upgrading, I pause Cloudflare on our site. The upgrade process is OK. And then I enable Cloudflare and then I login the Admin CP.
Then I notice that from time to time, the Admin CP will ask me to login repeatedly, or some frames requires to login.
So how to setup the rules or other configurations so that Cloudflare can work with vBulletin 5.7.2?
