not sure if its working, i see one webp file, but the rest are jpegs etc

also my page speed has actually gone slower since installing this plugin…

It is working – all jpegs are delivered as webp images in Chrome.

How do you measure the page speed?

If speed has gone done, it must be because it is currently a PHP script that does the redirection. In the next release (0.9.0), the redirection will be made in the .htaccess. If you cannot wait for the next release, you can insert the rules manually in your .htaccess file before the WebP Convert rules. cantoute posted some rules here: https://github.com/rosell-dk/webp-express/issues/94. Note that WebPExpress inserts its rules in the .htaccess in the wp-content folder, not in root.

Regarding cloudflare, see this topic: https://www.ads-software.com/support/topic/worked-on-staging-but-not-working-on-production/

I love the idea of this plugin, but its breaking my site on many browsers and i cannot work out how to get it functioning with cloudflare without using enterprise. I will have to deactivate and hope some fix arises in the future.
