 * when I activate the PageSpeed ​​Ninja plugin, in the source code of my site, 
   it generates links to scripts that do not exist.
 * Does anyone know how to fix this?
 * /s/3825bf.js
    /s/38f494.js /s/65a683.js
 * Example:
 *     ```
       <script ress-src="/s/38f494.js" type="text/ress"></script>
       <script ress-src="/s/3825bf.js" type="text/ress"></script>
       ```

 * `\s` is directory where PageSpeed Ninja stores combined/minified JavaScript and
   CSS files. Do you have this directory at all? (it may be that your website root
   directory is read-only and PageSpeed Ninja installer wasn’t able to create that
   directory automatically).

 * Perfect! That’s right, I granted the necessary permissions and I reinstalled 
   the plugin and it worked perfectly, the directory / s was created and error 404
   was solved.
 * Thanks
