I tried everything but can't make them to work. They were working when I installed the plugin, but stopped after a couple of days (automatically - I made no changes). Then I checked the nginx.conf file, the permissions to the wp-content folder and the nginx.conf file itself. Everything is fine, but the plugin shows the two errors. I restarted nginx too - a couple of times. But no gain.
- It appears Page Cache URL rewriting is not working.
- It appears Minify URL rewriting is not working.
Hope to get a solution soon.
