[Plugin: W3 Total Cache] Buggy cache problem with WP 3.3

Hello,

The plugin was installed and working perfectly on 3.2.1. After upgrading to 3.3 this morning I started to see some strange problems, uninstalled W3, then tried to reinstall it. Now many cache problem occurs. The first one is W3 told me to put ‘WP_CACHE’, I put it back, and W3 doesn’t see it. Tried many times, even tried to chmod 777 wp-config and let W3 write it, it did write it, but can’t read it. I restarted apache server and now it can see it. The preivous problem occurs on every change I did in W3 setting pages, any change is not read until I restarted the server. I finally disabled it, and now the site is acting normall, but sadly without W3 performance steroids 🙁

I have php 5.3. Memcached, APC all enabled.

Let me know if you need further details.
