I entered my www and it turned out that part of the home page was missing – as if someone had “removed” it. For a few days – when you were removing the problem with error 505 nothing happened. Is there any way to restore the missing elements? The problem concerns only the home page.
Navigate to Elementor > Settings > Features and activate the Containers option. Then check if the issue is resolved.
Navigate to Edit with Elementor > History > Revisions to restore a previous version. https://ibb.co/6Rz5NT9p
If you have a website backup, you can restore a previous version from your hosting provider or backup plugin. Since this issue started after fixing error 505, there might have been an unintended change.
