I have to wait a few days.
This was usually what was needed after clearing the cache

Done.

Yes, in other plugin (WP Super Cache) works fine

I have fluentSMTP plugin. Of course, all notifications are checked.

After downgrading the emails started.

After downgrade to 1.1.6 everything is ok

NO. I only use the plugin. I have it on multiple sites and all have the same problem. After upgrading from 1.1.6 to 1.1.7, the cache cannot be cleared (simply nothing happens – the cache is not cleared). Hence, no content can be updated because the change is not visible.

New version will be 1.1.6 or still 1.1.5?

Sure, its kapuga.pl

Yes, i using polylang.

Of course 5 stars. The plugin works great. I was the one who made a mistake in setting up the theme.

Thank you for your replies.
It turned out that the theme settings were causing the problem. I had to disable the DOM header check for mobile devices

I only have it marked:

Cache System:

Logged-in Users

Update Post

Disable Emojis

Same problem here.
New action dont save.
