In my plugin settings I have checked “Pass Thru (without rewrites in .htaccess files or Nginx configuration)”, now I manually add this code
# BEGIN WebP Converter
# ! --- DO NOT EDIT PREVIOUS LINE --- !
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_ACCEPT} image/webp
RewriteCond %{DOCUMENT_ROOT}/wp-content/uploads-webpc/$1.jpg.webp -f
RewriteRule (.+)\.jpg$ /wp-content/uploads-webpc/$1.jpg.webp [NC,T=image/webp,L]
RewriteCond %{HTTP_ACCEPT} image/webp
RewriteCond %{DOCUMENT_ROOT}/wp-content/uploads-webpc/$1.jpeg.webp -f
RewriteRule (.+)\.jpeg$ /wp-content/uploads-webpc/$1.jpeg.webp [NC,T=image/webp,L]
RewriteCond %{HTTP_ACCEPT} image/webp
RewriteCond %{DOCUMENT_ROOT}/wp-content/uploads-webpc/$1.png.webp -f
RewriteRule (.+)\.png$ /wp-content/uploads-webpc/$1.png.webp [NC,T=image/webp,L]
</IfModule>
<IfModule mod_headers.c>
Header Set Cache-Control "private"
</IfModule>
# ! --- DO NOT EDIT NEXT LINE --- !
# END WebP Converter
in .htaccess file in the /wp-content directory
and this code:
# BEGIN WebP Converter
# ! --- DO NOT EDIT PREVIOUS LINE --- !
<IfModule mod_mime.c>
AddType image/webp .webp
</IfModule>
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/webp "access plus 1 year"
</IfModule>
<IfModule mod_headers.c>
Header Set Cache-Control "private"
</IfModule>
# ! --- DO NOT EDIT NEXT LINE --- !
# END WebP Converter
in .htaccess file /wp-content/uploads-webpc directory
and now nothing changed( I tried to deactive/active plugin and also nothing happened
