WebP Express with Elementor and WP Rocket

Hi there,

first of all, I really like your plugin, and it works great!
I use it pretty often, and it’s one of those plugins that just does what it’s supposed to do.

But a few days ago I’ve encountered a problem. I guess it’s the combination of plugins I use: WebP Express, Elementor, WP-Rocket.
We all know that Elementor has a problem with WebP images because the background images are defined in a separate CSS which WebP Express can’t edit.
I’ve read in an older post that you’ve found a workaround for this, with Elementors advanced CSS rendering and the “Replace image URLs” option.
But here’s my issue:
This only works without caching. For a few reasons, I have to use WP-Rocket.
So I’m caught between a rock and a hard place.
Use caching without WebP images, or replace images with WebP without caching.
Maybe you can help me out,
you have any ideas?

Kind regards
