ws420 edited a comment on issue #1681: Uncacheable content, preventing rewriting of image URL: https://github.com/apache/incubator-pagespeed-ngx/issues/1681#issuecomment-594285089 Update: - We removed all pagespeed directives in nginx to make sure the module is enabled only for Apache - FetchHttps is enabled with the correct directory for the SSL certificate - nginx is still in proxy mode because we are unable to completely disable it in Plesk - We disabled all plugins in WordPress - Cloudflare is paused & respect original cache header. Cache is purged. - htaccess = Header set Cache-Control "max-age=3600, public" These changes seem to have helped. For the first time we see webp images!! GREAT! The debug mode is also fully working again However, even if most of the images are converted to webp, we are still seeing 4xx errors for a lot of images  In this example, the images from the first post are successfully converted to webp but the images of the second post have 4xx errors Thanks so much for your help
