Live link is different from the preview and edit. The hamburger menu in the header is fully opened and the icons are very big. It seems like something in CSS (or JS?) doesnt’ work.
I tried to regenerate CSS and data from Elementor > Tools, after that live links works for the first time, but after I click something and change page, I have this problem: Fatal error : Uncaught TypeError: Cannot access offset of type string on string.
If I regenerate CSS and data it works again but once again if i change page I have the same problem.
If you view the live link in an incognito window, different browser, or using a cache-busting string (Adding /? followed by any 4 random characters /?1234 for example) does that return it to what you want to see?
It sounds like there is still some cache stuck somewhere since it looks normal in the backend but different on your Live Link. As another test can you view the live link on a phone or tablet that’s not connected to WiFi? If it looks normal there, then it could be your caching that is getting in the way.
There are some different things to try and get around network caching. Restarting your device, restarting the network router/modem, or using a VPN connection.
This isn’t uncommon since Live Links don’t match your Local Site URL (ie: mysite.local), so Local attempts to rewrite these on the fly. Live Links is broadly compatible with many themes, plugins, and custom code snippets. However, some images, front-end assets, or other HTML elements may be missing from your site when viewing it over Live Links. You can try these steps to fix those up:
Run the following WP-CLI command wp search-replace 'SITEURL' 'LOCALURL' --skip-columns=guid
Disable certain types of plugins: caching, security, force HTTPS/SSL
If you’re still having trouble, ultimately what you could try and do if you need to share the site is get it into a Demo somewhere. For example, Flywheel has a free 14 day Demo option that you could push it to Demo Site
