WebP image conversion problem

hello everyone i have ispconfig 3.2.2 with apache2, i installed a plugin on one of my wordpress sites to convert images to webP format, the plugin gives me this message "The rules have been applied, however, the images have still not been converted to WebP. We recommend to contact your server provider to know more about the cause of this issue." how do i enable this feature?

 

I don't think the message seems clear, also I have tried more than one plugin for converting images to WebP, actually none have succeeded in the conversion, so I guess it is a problem with my system ..

 

I connected to the support of the last plugin I installed, some users complain about the same thing, they also say that on some hosting the plugin works correctly and in others it doesn't, however the plugin itself does not give other indications besides what I have indicated in post # 1, you say that maybe a script or a php module would be needed, but with my skills I don't know where to put my hands, consider that I installed my server following tutorials so I let you imagine my level of programmer

 

does it convert the images on upload? when someone tries viewing one? or do you have to tell it to convert an image?

try triggering whatever is required to get it to start a conversion and then look in the websites error log file, if there's some php version / syntax change incompatibility or missing php module, there should be something in the error log about it.

 

In fact I solved it so, I contacted support with their instructions I solved it by modifying the vhost file of my site by pasting the code provided by them, the file is in the directory /etc/apache2/sites-available/example.com.conf

 

ok, as I wrote in the previous post I went to the directory below and I pasted the code # BEGIN SMUSH-WEBP that the plugin developers gave me just before the line <Directory /var/www/maysite.it/web>

Code:

root@server:/etc/apache2/sites-available# less maysite.it.vhost
              
# BEGIN SMUSH-WEBP
<IfModule mod_rewrite.c>
 RewriteEngine On
 RewriteCond %{DOCUMENT_ROOT}/wp-content/smush-webp/disable_smush_webp !-f
 RewriteCond %{HTTP_ACCEPT} image/webp
 RewriteCond %{REQUEST_FILENAME} -f
 RewriteCond %{DOCUMENT_ROOT}/wp-content/smush-webp/$1.$2.webp -f
 RewriteRule ^/?(.+)\.(jpe?g|png)$ /wp-content/smush-webp/$1.$2.webp [NC,T=image/webp,E=WEBP_image]
</IfModule>

<IfModule mod_headers.c>
 Header append Vary Accept env=WEBP_image
</IfModule>

<IfModule mod_mime.c>
 AddType image/webp .webp
</IfModule>
# END SMUSH-WEBP
                <Directory /var/www/maysite.it/web>
                                # Clear PHP settings of this website
                                <FilesMatch ".+\.ph(p[345]?|t|tml)$">
                                                SetHandler None
                                </FilesMatch>
                                Options +SymlinksIfOwnerMatch
                                AllowOverride All
                                                                Require all granted

                                # ssi enabled
                                AddType text/html .shtml
                                AddOutputFilter INCLUDES .shtml
                                Options +Includes
                </Directory>

 

sorry how this thing is done

 

you shouldn't need to add those to your vhost config.
the plugin should have automatically added those to the .htaccess file in the root of your wordspress site.

it probably failed to do that because it didn't have permissions to write to that file, if you've made the .htaccess file owner read-only on all your wordpress sites, your going to have more problems... especially if you use plugins like wordfence, wp-total-cache etc which will expect to be able to add lots of rules into that file.

 

I had done it manually but it didn't work
