    Hm.. Been using ewww for years, but lately my webp delivery stopped working. I’ve been using the .htaccess method.

    Insertion successful, but self-test failed: WebP response failed mime-type test

    LiteSpeed web host, PHP 7.4, WP 5.6

    Are you able to reproduce?

    Best regards

    That means the rules don’t work with your site (as-is). Try moving them either above or below the default WordPress rules (depending on where they are now), as the ordering can make a difference with Litespeed sometimes.

    Thank you for your feedback ?? I got it solved.

    Kind regards

    @oldrup I’m getting the same issue on OpenLiteSpeed, a clue to your solution would be greatly appreciated please. When I checked the JS WebP Rewriting checkbox references to webp were made in the data-bg-webp property of background images but no reference inside img-tags.

    @nickwuk Sorry I didn’t elaborate. I was already using the LiteSpeed caching plugin, and as I learned that it too can create and server wep images, I chose to go that route. On non-LiteSpeed servers I still use EWWW where it makes sense.

    All the best
