Its very weird. Everything appears to be working in the W3 Plugin. There are no errors or complaints. I'm trying to use memcached for page, database, and object caching. I turn on the debug mode but no comments spits out in the html source.
It looks like its communicating with memcached OK. When I watch what memcached I do see calls for the page cache, database cache, and object cache (although That might not mean its working, just calling?).
I've loaded the default theme and disabled all plugins with the same result.
I've checked the wp-config file to make sure define('WP_CACHE', true); is there. I trashed the current wp-config and used the sample config file with all defaults. Still nothing.
What other pages would have settings in them for WP? I can't think of much else to try with that install.
So then I set up a fresh install of WP and W3. Everything is working as expected. I see the comments in the html even without the debug mode on. So server setup I assume is OK.
Any suggestions would be great. Thanks!
