I am using vBulletin 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 installing, I pause Cloudflare on our site. The installation 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, like below:
I have already added the page rule based on the post How to setup Cloudflare rules for vBulletin 5.7.2, as below:
But that does not work.
