 * Good morning,
 * I am testing WebP Express on a multisite installation. So far, I am not having
   any luck – all self tests seem to work, but the site continues to provide (mostly)
   jpegs (actual jpegs).
 * Interestingly, images contained in the theme used itself seem to get converted,
   it’s just content that doesn’t.
 * I’d appreciate any tips on how to debug this.

 * [@nilsjeppe](https://wordpress.org/support/users/nilsjeppe/) Holla! Can you provide
   your server config (LAMP/LEMP/etc) and settings of your installation of wp and
   webp express?
    I have multisite and this plugin works well.

   for your reply 🙂
 * It does seem to work somewhat. Test images work, and so do some images hard coded
   in themes, apparently. In the webp-express directory, I see:
 * webp-express]# find . |grep -i \.webp$
 * ./webp-images-bigger-than-source/themes/duster/images/search.png.webp
    ./webp-
   images-bigger-than-source/themes/webp-express-test-images/Bd1ZSK.JPEG.webp ./
   webp-images-bigger-than-source/uploads/webp-express-test-images/rllyVA.JPEG.webp./
   webp-images/plugins/cookie-law-info/admin/modules/cookies/images/cli_icon.png.
   webp ./webp-images/plugins/cookie-law-info/admin/images/support.png.webp ./webp-

 * (grep for brevity). So the plugin does run. it can convert and write files, etc.
   but it’s ignoring any and all “content” images.
 * I do make heavy use of child themes, mainly to prevent calls to fonts.google.
   com, which may be noteworthy. It does not seem to make a difference though (a
   site that doesn’t use a child theme also doesn’t appear to convert images).
 * There’s really nothing weird about my lamp stack. It’s apache + MariaDB + php-
   fpm. PHP version is 7.4 – I tried 8.1 and 8.0 but apparently those cause issues
   with WP and various plugins and themes so that’s not an option.
 * Apache config is absolutely minimal. 2 vhosts per site, one http that redirects
   to https, one https that points at wordpress:
 * <VirtualHost ip:80>
    ServerName [http://www.example.com](http://www.example.com)
   ServerAlias example.com
 *  DirectoryIndex index.html index.php
    DocumentRoot /home/www/wordpress/htdocs/
 *  CustomLog /var/log/httpd/wordpress.combined.log combined
    ErrorLog /var/log/
   httpd/wordpress.errors.log
 *  # mod_deflate
    SetOutputFilter DEFLATE AddOutputFilterByType DEFLATE text/html
   text/plain text/xml text/css text/javascript application/javascript RewriteEngine
   on RewriteCond %{SERVER_NAME} =example.com [OR] RewriteCond %{SERVER_NAME} =www.
   example.com RewriteRule ^ [https://%](https://%){SERVER_NAME}%{REQUEST_URI} [
   END,NE,R=permanent] </VirtualHost>`
 * <IfModule mod_ssl.c>
    <VirtualHost ip:443> ServerName [http://www.example.com](http://www.example.com)
   ServerAlias example.com
 *  DirectoryIndex index.html index.php
    DocumentRoot /home/www/wordpress/htdocs/
 *  CustomLog /var/log/httpd/wordpress.combined.log combined
    ErrorLog /var/log/
   httpd/wordpress.errors.log
 *  # mod_deflate
    SetOutputFilter DEFLATE AddOutputFilterByType DEFLATE text/html
   text/plain text/xml text/css text/javascript application/javascript
 * Include /etc/letsencrypt/options-ssl-apache.conf
    SSLCertificateFile /etc/letsencrypt/
   live/example.com/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/example.
   com/privkey.pem
 * Header always set Strict-Transport-Security “max-age=31536000; includeSubDomains;
   preload”
 * </VirtualHost>
    </IfModule>`
 * The vhost for *.blog.example.net is identical, except for the domain name. (Reason
   for separate vhosts is the use of letsencrypt SSL certs, I can’t work with SANs.)
 * The only “nonstandard thing” I set outside the vhosts is:
 *  ExpiresActive on
    ExpiresDefault “access 1 day” Header append Cache-Control “
   public”
 * I really doubt that’s related to this issue.
 * Relevant plugins might be:
 * GDPR Cookie Consent – doesn’t seem to affect the issue (tested on/off)
    Autooptimize–
   doesn’t seem to affect the issue (tested on/off) Jetpack – without the CDN/image
   acceleration options WordPress MU Domain Mapping – For, well, domain mapping (
   I am not even sure this is still needed)
 * Webp Express settings:
 * Operation mode varied (default)
 * Scope All Content
    Image types both jped and png Destination folder separate 
   File extension append (it’s greyed out, can’t be changed) Destination structure
   image roots Cache control set private one day Prevent using webps larger than
   original disabled
 * I haven’t enabled “convert on upload”, and I haven’t tried “bulk convert”.
 * Enable direct redirection to existing converted images enabled
    Enable redirection
   to converter enabled Create webp files upon request enabled
 * web service and alter html are disabled.
 * Available Conversion methods are ImageMagick (php extension) and gd.
 * Side note, if I enable “alter html”, it does attempt to replace content images–
   it alters the html code, but they’re broken (because the images do not exist).
   Custom header image is untouched and still a jpeg.
 * Hmm. If there’s anything else that might be relevant… please let me know.
