Why did WordPress start overwriting posts?

Question

Programming

Gentlemen programmers - layout designers some time ago had problems with creating new entries in the WP admin panel. Who faced.
The bottom line - I create a new entry, a link is generated, I publish it - everything is fine. Then here I click on "add a new entry" and enter the name of the text, the same link is generated as in the previous entry, respectively, the entry is overwritten when published.
The solution was found by disabling the cache using the plugin for FF Web Developer.
But after all, everything worked before, moreover, this situation is not on one PC in the studio!
Any advice?
