I'm installing vBulletin v5.7.2. PHP version is 7.4.2
Our website is https://www.example.com and the vBulletin forums are installed at https://www.example.com/forums/ . We enable Cloudflare Pro for the whole domain example.com, so the forums subdirectory is also affected.
Before starting installation, 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:
If I pause Cloudflare on our site, then wait for about 10 mins, then everything will be OK again.
I search online and find this post https://www.vbulletin.org/forum/showthread.php?t=324748 and this one https://forum.vbulletin.com/forum/vb...udflare-issues , both said it is necessary to set a Cloudflare page rule to solve the issue.
So I setup a page rule as below, trying to disable everything possible:
But that still not working.
I have added the following lines to config.php:
$config['Misc']['proxyiplist'] = 'all';
$config['Misc']['proxyipheader'] = 'HTTP_CF_CONNECTING_IP';
But still not working.
