I've been searching the web a lot and nobody seems to have this problem: I'm using ProCache (3.1.4) on Processwire 3.0.165, but it doesn't seem to work. It always creates and delivers a new HTML file, despite the existing one in the cache. I'm logged out from Processwire, use even another browser. The license key is for the developer version, so it should work with any website. All templates are checked to be cached and the cache files are properly created, but not used. What could be a solution for that?
