Error codes: rewrites_cached

Hi there, thanks am testing the plugin, when installing we get Error codes: rewrites_cached. A few google searches bring me to an article suggesting to disabling Universal SLL in Cloudflare which gets rid of the error. Then running the plugin to convert all images we start getting errors on all images because SSL is no longer active. When we load the website it comes up with an insecure message, not able to contact to SSL.

Then we enable Universal SLL, five minutes later the site is back.

Is there any workaround?

Also I noticed in one of the FAQ’s that this setup with WebP Converter may not work as Clouedflare does not automatically convert images to WebP. is that right?
