WordPress Homepage won't show new blog post in visitors

Question

I am facing a problem where new blog posts won't show up on the homepage of the site. The website is running with the latest PHP and in WordPress powered by Plesk in a VPS server.

Here's what I've tried so far:

• Deactivate and even reinstall all plugins.
• Deactivate and even reinstall the theme (I also changed the theme with another).
• Clearing both WordPress's cache and CloudFlare's cache.
• Change CloudFlare to "Developer Mode" to make sure there's no problem with Cloudflare.
• Change cache plugin (currently, I have the WP Rocket, but also tried many others).
• Reinstall WordPress using the "WordPress reinstall" button in the "Updates" page.
• Changing PHP versions.
• Renaming the .htaccess file.
• Removed all files with cache in the /root/ folders.
• Trying visiting the website with "Private window" and also from different laptops, PCs, smartphones and IPs. Same.

I even put the website in the "under construction" page and it just won't show up. As an admin, I can see all the latest posts, but as a visitor, nothing really updates. For example, the Instagram widget won't show up the new images that I have uploaded, the slider doesn't work and nothing actually gets updated.

In the browser's console, I do see a few errors (as an admin I can't), and it's the same error for many plugins:

Uncaught SyntaxError: Unexpected token '<'

This error goes to /wp-content/cache/busting/ and here's the link to the website that is facing the problems: https://artdecorationcrafting.gr/

Any help will be much appreciated!

The problem was CloudFlare and Ezoic. After changing the nameservers back the the main ones, fully removing CloudFlare and Ezoic, the blog started working again.
