Well, I got Page Cache enabled as "disk enhanced", and also minify. I dont get any error messages at all, however, my server still gets overloaded (I have a limit of 25 processes max at HostGator, and it goes over that whenever I got 30, 40 users coming in at once).
So, I considered my Page Cache not working, although the minify is clearly working. When I turn on the Debug Mode for Minify, I see the details on the bottom of every page, and thats fine. But if I turn on the Page Cache debug, I get an error message on the top of the config page:
W3 Total Cache error: It appears Page Cache URL rewriting is not working. Please verify that the server configuration allows .htaccess
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.
Technical info:
.htaccess file contains rules to rewrite url http://www.layback.com.br/w3tc_rewrite_test into http://www.layback.com.br/?w3tc_rewrite_test which, if handled by plugin, return "OK" message.
The plugin made a request to http://www.layback.com.br/w3tc_rewrite_test but received:
200 OK
instead of "OK" response.What is with that?
