After activating Cloudflare, I’m facing some problems on my site
So you haven’t given an explanation of what the issues are, just posted screenshots.
Providing the domain for the site might also help garner more clues to assist you.
I apologize, but would my explanation be better than the detailed screenshots of the problem!
This is my domaine
Currently I stopped Cloudflare service temporarily and the previous problems disappeared
Detailed text is better than detailed screenshots. However…
Perhaps this thread might help
As for cache, this might depend on the cache settings for the site in Cloudflare and on the origin server.
