Hello!
I’ve got some problem with caching. When I use icognito mode to check my website, everything is wrong. Check image. No icons, the images are bigger etc.
Yes right now it is. But if I don’t purge the cache time to time I get this. I’ve added so it purges everytime i update my site. But seems not to work.
It just sounds like you have Smush set to convert images to WebP, but not change the file extension. So when an older version of Safari visits the site, it can’t load a .png file that’s actually WebP.
I suggest you disable the WebP conversion at your site and see if that fixes the issue.
