Delete additional cached version for WebP image

The Cache Enabler plugin doesn’t convert images to WebP. When the Cache Enabler creates an additional cached version for WebP image support it only creates a separate cached page (e.g. index-webp.html) in wp-content/cache/cache-enabler/example.com. This can be deleted by clearing the Cache Enabler cache.

Interesting. Now I wonder if Shortpixel is the one creating that extra .jpg.webp file.

Reason why I am asking here is Shortpixel referenced your plugin + theirs to display webp files.

Let me dig more into this.

This is very interesting. Both you and SP support had now indicated that neither of your plugins create these *.jpg.webp files.

Let’s how much more testing I can do to try and find whatever is creating these extra files before I disable either plugins.

If you have any more advice, I am open for more troubleshooting on my end.

I have done more testing and here is what I have found. Since Shortpixel does create x.webp files, I disabled Cache Enabler and tried to upload images again. Only x.jpg and x.webp files are crated. When I enabled Cache Enabler, the above files are created alongside x.jpg.webp files. Deleting the image inside WordPress > Media > Library removes the first 2 on the server but leaves behind an orphaned x.jpg.webp file.

From this, I can only surmise that having both SP and Cache Enabler running causes this issue. The only reason I am trying this combination is that the SP blog mentioned that Cache Enabler could be used to server webp files while SP created them.

Maybe this is something that has not been reported yet?
