have several problems with conprestashop 1st when updating the application to prestashop 1.7.6.8 gives error 500 when I have extra power available on the web server 2ºI have a problem with the small photos in prestashop 1.7.6.4 and with warehouse 4.3.4 when you make a product list, for example, hp toners, the list with the products without the photo on any of them will appear. do not load them and give an error on smarty. on the product photo if the photo appears. 3 I also spent my time converting all the photos in the boxes to the large format of prestashop 1358x 620, I compressed them leaving them uglier, and slowing down the page and doubling the size in the image folder. I leave a screenshot of the errors There are a lot of errors in myapplication, here you can see the DevTools output: [login to view URL] [login to view URL] There are errors like: Failed parsing 'srcset' attribute value since it has an unknown descriptor. This is related to your theme and how it is parsing resources. I would like someone to help me correct this error and others with the cache that makes my page not work properly Translated with [login to view URL] (free version)
