Hi. I have a problem with CPU load, it's over the line of 10% permitted on my hosting. So I tryed to swith on caching with WP Super Cache. I activeted WPSC with defaults(then experiment with some parameters) and CPU load not go down, but a little up. It looks like the working of plugin makes load of CPU.
-ON WP Cache and Super Cache enabled
-Don’t cache pages for known users. (Logged in users and those that comment)
-Clear all cache files when a post or page is published. (This may significantly slow down saving of posts.)
-Only refresh current page when comments made.
-Expire time:7200 seconds
Then I have tryed to reinstall plugin. I've done "1" in uninstall.php. But when I clear necessary for WPSC strings from .htaccess works only the main page of my site, all other links goes to page 404, including links from search engines. So I leave this file not clearing. How to clear it?
