I noticed when using caching plugins like Litespeed cache or shortpixel optimization and turning on a function to serve webp images when available that this doesn't work for Metabox image advanced field.
The images added from the Image Advanced field are served only as jpg in this case.
How can i enable this or include this?
Could anyone help? I do have a snippets plugin available if code needs to go in a header and such.
Did you try to test uploading webp images with other image fields or featured image of WordPress? Does the issue happen with only the image_advanced field?
