Hello. Thank you for contacting the Toolset support.
Yes - I checked on your site and I can see in the backend I can successfully create a view but its not get displayed on the frontend. I'm downloading the duplicator package you shared.
No, there is no server caching. It is shared hosting, but the most popular here in Denmark and usually has no issues at all.. I downloaded the log file as it seems there are some 404's. Maybe thats the reason.. You can find it here: hidden link

I do not know why its showing 404 - looks like its blocked by your server? those URLs should work without any issue.
In order to minimize the cause of the issue:
- What if you try to load the same site on a different server or on your localhost? Does it make any difference?
