Many 404s

    Hi,
    I recently installed ShortPixel Image Optimizer and ShortPixel Adaptive Images on a site I’m optimizing. I’ve used Image Optimizer previously, but I’m using Adaptive Images for the first time.
    Now my Moz report is suddenly showing 140 404 errors related to JPGs. I’m not sure why this happened. Did one of the plugins change filenames?
    Yikes! How do I fix these errors without losing all the benefits of optimization? Setting 140 page redirects would be an onerous task.
    Help, please.
    Thanks.

    Hi, @akubrin!

    ShortPixel Image Optimizer only replaces the physical files; it does not modify the URLs of the images nor edit the page’s code. Moreover, it will not replace the physical file if it cannot make a backup before.

    I also checked your site and all images look good to me.

    If you are still facing this problem, please let us know step by step how we can reproduce it. I also suggest making sure you flush your website’s cache and then try again. Please do it in this order:
    – Cache plugins (WP Rocket, LiteSpeed Cache, SG Optimizer…)
    – Server cache (SiteGround, Bluehost…)
    – CDN cache (Cloudflare, StackPath…). Please do it from your CDN’s dashboard, not through your cache plugin or hosting dashboard.
    – Browser cache (Chrome, Firefox, Edge, Safari…)

    Thank you!

    Hi @sixaxis!
    Thank you for checking in.
    I’ll try the solution you propose. I can easily clear the plugin caches. I’m not sure how to clear a server cache, though. Can you advise?
    The site does not have a CDN and is unlikely to need one since its audience is geographically concentrated.
    I don’t think my browser cache is the issue. These errors are reported by a site crawler. The images also show up fine in my browser.
    I wonder if this issue is caused by ShortPixel Adaptive Images. Perhaps I should restore the originals, deactivate Adaptive Images, then reoptimize. What do you think of this idea?
    Thank you.

    Hey @akubrin!

    Regarding server cache, it all depends on your host. Some hosts provide some server cache (like SiteGround, who provides you with a button to clear cache in their control panel) and some hosts don’t, so the best way to find out is ask their support team ??

    If the errors are reported by a site crawler, but the images show up fine in your browser, perhaps the site crawler is just giving a false positive? It would be worth to know what those URLs are, and where they are located.

    Regarding Adaptive Images, restoring the originals and re-optimizing will not give any benefit. I think we first need to know what I told you: what are the URLs? where are they located?

    Maybe this way we can find out more.

    Best,
