Had double checked the Minify cache code (in public_html/wp-content/cache/minify/.htaccess) and Page Cache code (in public_html/wp-content/cache/page_enhanced/.htaccess) was there.
But. The notice still shown as above and below:
It appears Page Cache URL rewriting is not working. If using apache, verify that the server configuration allows .htaccess. Or if using nginx verify all configuration files are included in the configuration file (and that you have reloaded / restarted nginx).
Technical info.htaccess file contains rules to rewrite url http://bigbestbuy.asia/w3tc_rewrite_test into http://bigbestbuy.asia/?w3tc_rewrite_test which, if handled by plugin, return "OK" message.
The plugin made a request to http://bigbestbuy.asia/w3tc_rewrite_test but received:
Operation timed out after 5001 milliseconds with 0 bytes received
instead of "OK" response.
Unfortunately disk enhanced page caching 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.
