I have configured a Magento 2.0.5 website with Cloudflare. The issue is some admin pages are not loading correctly. For example, catalog management page cannot load products list, user management page cannot load user list. Other admin pages work OK. It seems related to XHR queries used in those pages. But I checked those XHR queries, all returned correct responses.
I can only get those pages working by enabling Cloudflare development mode. I also configured Cloudflare Page Rules to by pass cache for admin pages, but it doesn't work.
Anyone has encountered the same issue before?
