Browser Console Error

    Hi, I’m testing this plugin out on a development site. I have an image set for the home page, but see the following console error:

    Preload of xxx.xxx.xxx ignored due to unknown “as” or “type” values, or non-matching “media” attribute.

    Looking at the source code, the type="" attribute is indeed empty. Does this impact the page’s performance?

    It also doesn’t appear that the mobile image is preloaded. Then again, I’m checking on a desktop.

    I’m using the GeneratePress theme. Also using the Block Visibility plugin to determine which LCP image shows up on a given device.

    The page I need help with: [log in to see the link]

    Hi Eric,

    Are you using any plugin to generate any sort of WebP? Or serve images differently?

    I think there’s a potential bug in something like WebP Express in that it doesn’t detect the file type. I am working on a fix that will allow you to specify the file type explicitly, which will be a bit of a workaround but seems to be a bit of an edge case (though oddly reported twice in the last 24 hours, so I suspect it may be something to do with WordPress 6.4.3…).

    The mobile image will only be preloaded on mobiles (or if you send a mobile agent, basically using wp_is_mobile()), so that’s expected behaviour.

    Hi Rhys,

    Thanks for your help!

    About the only thing different here is that I’m using GeneratePress Elements to create the hero image at the top of the page:
    https://docs.generatepress.com/article/block-element-overview/

    Their Elements are separate posts that get merged into a page via a hook. So maybe that’s it?

    Otherwise, there’s no webp image conversion going on.

    Thanks!

    Hi Eric,

    Thanks for your patience.

    I’ve got a fix, but I’ve been unable to push it to the WordPress repository just yet, but I’ve uploaded it to Github if you want to preview it and comfortable with downloading a plugin from there?

    I should push it in the next week or two when my life is a bit less hectic!
