W3 Total Cache error: for minify and pagecache

Hello,

i m having this 2 error logs when i enable my w3tc debug mode.

1st

W3 Total Cache error:It appears Minify URL rewriting is not working. Please verify that all configuration files are included in the configuration file (and that you have reloaded / restarted nginx).
Unfortunately minification will not function without custom rewrite rules. Please ask your server administrator for assistance. Also refer to the install page for the rules for your server.
