Unfortunately not. I know that others are seeing it, but on multiple browsers on multiple devices on multiple networks, I cannot see it. I have no explanation for it, but it's true. I don't know how a cache could target multiple browsers, unless it was something like Cloudflare, which I use, except that I've cleared that cache multiple times. I disabled jetpack's optimization, and turned off pagespeed in apache, and there is no difference for me. In a FB group for the theme I use, most people also saw the image, but at least one person is seeing what I'm seeing. It's maddening as I don't know what the common factor is.
