Uninstalling Does Not Fully Uninstall

  • While most users seem to have a positive experience with Hummingbird, mine was a less than great. After deciding the performance gains were negligible, I decided to deactivate the plugin, but that resulted in countless console errors, most of which looked like this: GET …xxxxx/wp-content/uploads/hummingbird-assets/48fb21d6236fb7954deff857cb46e34a.js [HTTP/2 404 Not Found 789ms] I followed instructions on doing a clean uninstall, but that didn’t help, leaving a site with 10-15 of the aforementioned JS errors on every single page. After realizing there was no realistic way to remove them all, I ended up having to roll the site back, so just a heads-up this may be a one way trip depending on your site, so back up before installing.

    Hi @jcd66672

    We apologize you faced such a problem. After the uninstallation of Hummingbird, all should go back to normal and no JavaScript assets should be called.
    About the “HTTP/2 404 Not Found” error, it may be caused by an extra caching layer either in the server or an external service like or similar to Cloudflare.
    Depending on the optimization needs of your site, further customization can be performed using the Page Cache and Asset Optimization options.

    There are several features that may require some extra configuration to get the most out of the plugin:

    • Enabling the text compression (GZip).
    • Add a preconnect to required origins.
    • Use the preload key requests.
    • Set the Page and the Asset Cache.
    • Optimize CSS and JS assets by preloading, combining or deferring
    • Eliminate render-blocking resources by moving critical CSS and JS inline and defer all non-critical JS/CSS.
    • Defer unused CSS – Defer the loading of CSS not used for above-the-fold content.

    Also you can integrate with Smush Pro to Lazy Load offscreen images which is a key recommendation in the Page Performance Tests
