Option “Only modified pages” does not work

Hello!

Thank you very much for the great plugin – very good speed and quality of work. But there is one problem, the solution to which has not yet been found.

The “Only modified pages” option in the plugin settings does not work.

As I understand it, when the page is refreshed, its cache should now be immediately flushed and refreshed, but this does not happen. The page is still shown to site users without any changes I made (until the cache lifetime specified in the settings expires).

At the same time, the load on the server is generally practically zero. The problem occurs both on the hosting and on the local server, where there can be no load at all.

Do not tell me what it might be connected with.

Thank.
