I raise this topic, trying to solve the problem on my own for about a week. I read the internet and nothing seems to help.
I installed and configured W3 Total Cache to optimize the loading of the site. Everything worked well until the next morning, and I found that my site was confused. I immediately deleted the plugin and deleted folders as recommended by Google. He fixed the site on a laptop, but responsiveness on mobile devices did not work. Sliders on the main page, font, style, everything is spoiled. I tested it on iPhone and Android, and the problem is the same. I tried to remove the plugin and delete the files as recommended here , but all in vain. Here's what it looks like on mobile devices: Could you help me a little bit to understand the problem and how to fix it?
