 * HI
 * I love the plugin! Great work.
 * Everything was working 100% – not sure when it broke. I use ShiftNav for my mobile
   menu. Sadly now, for some reason my image in my mobile menu is broken. NGINX 
   says 404 not found.
 * Everything else is working 100%.
 * Do you have any ideas?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fshiftnavpro-webp%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Yes, I see a 404 on the following URL:

 * I can see that you are using the new alter HTML option, with picture tags.
 * I guess that you have enabled “Reference webps that hasn’t been converted yet”
   and “Convert non-existing webp-files upon request”.
 * However, the “Convert non-existing webp-files upon request” option requires that
   you add an extra rule in your Nginx config. I have recently improved the Nginx
   rules in the FAQ, and there are also a rule for that. Check it out here: [https://wordpress.org/plugins/webp-express/](https://wordpress.org/plugins/webp-express/)(
   the “I am on Nginx” section)
 * You could also simply disable “Reference webps that hasn’t been converted yet”

 * The Nginx rules for making “Convert non-existing webp-files upon request” work:
 *     ```
       location ~* ^/?wp-content/.*\.(png|jpe?g)\.webp$ {
           try_files
             $uri
             /wp-content/plugins/webp-express/wod/webp-realizer.php?wp-content=wp-content
             ;
       }
       ```
   
 * (but you should add the other suggestions in the FAQ too)

 * Brilliant! Working like a charm… Thanks for your very quick response.
 * Let me give you some more info for your FAQ’s…. The lazy loading is also working
   with Lazy Load by WP Rocket. If I didn’t give you a review, I will do so now.
