Logo, thumbnails and photos not loading + mobile menu issue

Hi, I have discovered some issues with my site. I’m the using Generatepress (Avery) theme.

The thing is, when I’m navigating the site while logged in to my admin account in my regular browser, everything looks fine.

But when trying to load the page with another Chrome profile (where I’m not logged in), the site seems broken in several ways.

First of all the logo and the thumbnails aren’t loading at all. Also when entering an article, only sometimes will the featured images and blog photos load.

I first thought this could be an issue with either Litespeed Cache or Perfmatters plugins I’m using, as I had lazy loading of photos activated. I then tried to deactivate both of these plugins and see if it helped, but it didn’t. I also cleared Cloudflare cache to no avail.

In addition to this issue, I’ve also noticed that my site sometimes isn’t loading properly on mobile. Sometimes there will only be text loading (no design at all). And when the design is showing, the mobile menu isn’t working. Nothing happens when clicking it.

So I’m wondering what on earth can be causing all these issues, and how come I only notice them when I’m not logged in as admin? I’m not sure how long this has been going on, but now I’m wondering if all visitors to the site are experiencing these issues and how long it’s been going on.

Any help would be great, as I really need this fixed to make the site usable.
