Thanks for reply @isaumya
Now I back to standard CF plugin, cuz I have all the time people in my shop. But I can tell you more about problem.
In first time I was successful connected with your plugin, but I had problem with cart page (if u add sth there, cart was all the time empty).
Then I uninstall it and I configured CF plugin by Cloudflare. I want today back and try it again, but I have all the time “There is no page rule to delete” problem and cant run cache.
