![]() The image sizes you select will be compressed automatically upon upload if you have Automatic Compression enabled.

WordPress pros, on the other hand, achieve page speed in many ways and the benefits of duplicate images may be minimal. WordPress duplicate images are a net positive for most users – a simple exchange of storage space for faster page speed. Or add this filter to your child-theme functions.php or a mu-plugin:Īdd_filter( 'wp_smush_stop_background_processing', 'stop_background_processing' ). ![]() Add this constant to your wp-config.php file, just above the line that says “ That’s all, stop editing“:ĭefine('WP_SMUSH_STOP_BACKGROUND_PROCESSING', true).Remember to remove the code afterwards or you will not be able to run the bulk smush at all. If clicking that link still does not stop the process, you can try either of the following two code options. Change yoursite.tld to your actual domain name. If clicking the Cancel link does not stop the process for some reason, you can force it to stop by pasting this URL in your browser and refreshing the page.

If changing the settings doesn’t work or you don’t have access to the settings page, you can add this snippet of code to the functions.php file or add it as a separate plugin. Even though the solution in the trac ticket is one line of code, McGill says it will break a lot of site configurations. McGill confirms that the issue is related to a bug in the way WordPress builds URLs. Joe McGill, who helped lead the effort to get responsive images into WordPress, also responded in the forum thread and confirms Cree’s suggestion is correct, “If you’re running HTTPS on the front end, you should change the URLS for your home and site URL in Settings > General so they use the HTTPS scheme,” he said. If both the WordPress address and Site URLs don’t show https, it’s likely causing issues with responsive images in WordPress 4.4. Cree suggests users check their settings to see which URL type is configured. Inspecting the filename-element in Chrome or Firefox gets me thisĪs you can see, the image’s src is correctly set to https, whereas the srcset attribute is un-encrypted.Ĭhris Cree who experienced the same problem discovered that the WP_SITEURL and WP_HOME constants in the wp-config.php file were configured to structure URLs with http instead of https. Instead of an image,I get a filename printed out. Using 4.3.1 all content was https.Īfter upgrading to 4.4 images no longer load and the browser complains about mixed content. I recently switched my WordPress site to https after getting certificates from Let’s Encrypt. In a thread on the support forum, Brokkr explains the crux of the problem: If you notice images don’t load after upgrading to WordPress 4.4 and you use SSL on the frontend, you’re not alone.
