WordPress pages redirect to the homepage

Hello everyone,
On my WordPress site, the pages and posts redirect to the homepage. The issue is caused by the permalinks, but when I refresh the cache, the issue is fixed for about a week. After that, I have to repeat the process.
It would be great if this issue could be solved so that I would not have to refresh the cache every time. Could my permalinks be redirecting to the homepage for some reason?

The page I need help with: [log in to see the link]
