Not Working but Why?

I see images pointing to cdn.shortpixel.ai. So you disabled WebP Express and went with another solution?

I haven’t tested with Autooptimize.

Hi I would prefeer your plugin instead of the shortpixel one.
I switched now.
Mybe you can help me to get it run.

BR,
Chris

Ok. Which mode have you selected?

I can see that there is no redirection to the converter going on.
And no HTML altering either

If you have selected “Varied image responses”, some redirect rules should have been added in your wp-content/.htaccess. Does that file exist? If yes, please paste its content here

It might be that your Apache has been configured to disable .htaccess files. In that case, you need to copy the rules into your virtual host configuration (etc/apache/sites-available/your-site.com.conf)

It may also be that mod_rewrite isn’t enabled on your server.

Hi, It is the Varied image mode.

I have the .htacces file in the Folder. Here is the Copy:

# BEGIN WebP Express
<IfModule mod_rewrite.c>
RewriteEngine On

# Redirect to existing converted image in cache-dir (if browser supports webp)
RewriteCond %{HTTP_ACCEPT} image/webp
RewriteCond %{REQUEST_FILENAME} -f
RewriteCond %{DOCUMENT_ROOT}/wp-content/webp-express/webp-images/doc-root/wp-content/$1.$2.webp -f
RewriteRule ^/?(.+)\.(jpe?g|png)$ /wp-content/webp-express/webp-images/doc-root/wp-content/$1.$2.webp [NC,T=image/webp,E=EXISTING:1,L]

# Set Cache-Control header so these direct redirections also get the header set
<IfModule mod_headers.c>
<FilesMatch “\.webp$”>
Header set Cache-Control “private, max-age=31536000”
</FilesMatch>
</IfModule>

# Pass REQUEST_FILENAME to webp-on-demand.php in request header
RewriteCond %{HTTP_ACCEPT} image/webp
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^(.*)\.(jpe?g|png)$ – [E=REQFN:%{REQUEST_FILENAME}]
<IfModule mod_headers.c>
RequestHeader set REQFN “%{REQFN}e” env=REQFN
</IfModule>

# Redirect images to webp-on-demand.php (if browser supports webp)
RewriteCond %{HTTP_ACCEPT} image/webp
RewriteCond %{REQUEST_FILENAME} -f
RewriteCond %{QUERY_STRING} (.*)
RewriteRule ^/?(.+)\.(jpe?g|png)$ /wp-content/plugins/webp-express/wod/webp-on-demand.php?wp-content=wp-content&%1 [NC,L]

<IfModule mod_headers.c>
<IfModule mod_setenvif.c>
# Set Vary:Accept header for the image types handled by WebP Express.
# The purpose is to make CDN aware that the response varies with the Accept header, so it should not just use the URL as cache key, but also the Accept header.
SetEnvIf Request_URI “\.(jpe?g|png)” ADDVARY
Header append “Vary” “Accept” env=ADDVARY

# Set X-WebP-Express header for diagnose purposes
# Apache appends “REDIRECT_” in front of the environment variables defined in mod_rewrite, but LiteSpeed does not.
# So, the next line is for Apache, in order to set environment variables without “REDIRECT_”
SetEnvIf REDIRECT_EXISTING 1 EXISTING=1
Header set “X-WebP-Express” “Redirected directly to existing webp” env=EXISTING
</IfModule>
</IfModule>

</IfModule>
<IfModule mod_mime.c>
AddType image/webp .webp
</IfModule>

# END WebP Express

Is there an .htaccess file in the uploads folder? (rules in there will override rules in wp-content/.htaccess)

Is autooptimize enabled? If yes, could you try to disable it for a moment and see if that solves it?

Could you temporarily create a file “server-info.php” file in your root with the following content: “<?php phpinfo(); ” ? (dont add the “)

Can I also get the content of your .htaccess in root ?

OK there was a .ht file in uploads. I renamed it.
the php info file is created.
Chaching, Autooptimize everthing if off now.

I see that it works now.
So question is which of your actions made it work.

Curious to know the content of .htaccess in uploads !
My guess is that it an optimization created by Autooptimize to load images directly
