 * Hi, I have tested many cache plugins and yours beat them in Performance Score.
   
   Your plugins score 92% Performance in PageSpeed Insights while other score between
   67% and 83%.I have disable the option “lazy loading” of images because no image
   is loaded / shown. I saw that the url of the images is stucked in <noscript> 
   tag.If you have time, could you correct it plz ?Thx

 * Nice to read it works well for you Nicolas!
 * re. AO lazyload, it;
    1. in the img tag it replaces src= with data-src= 2. and
   it adds a new src= attribute with a placeholder svg image 3. and it adds the 
   lazyload class to the class attribute 4. and it adds lazysizes.min.js to the 
   HTML, which takes care of using the data-src attribute value to populate the 
   src 5. indeed adds the original img in noscript tags to ensure images are visible
   if/ when JS is not available
 * If images don’t load, the problem is not with (5) but somewhere in 1-4, but I
   would have it see broken somewhere to be able to comment/ help/ fix it. do you
   have a staging site where you could leave things broken for me to look at?
