After upgrading to WP3 W3TC slow down my site...
So I uninstalled it and removed everything like cache-config.php and the entry inside the wp-config.php.
If I now loading my site I got this:
Warning: Cannot modify header information - headers already sent by....header.php
on top of every site!!!???
I only get rid of this Warning if I reinstall the W3TC and disable the cache function ('cause I don't want it anymore).
So - what else does W3TC modify inside my Core or Database ?????
I just want nothing more than a clean deinstall of the plug.
Sorry this one was double posted,please, delete the first one!!
