Hi,
Just a heads up. I had to change all references in the wp-cache files from:
ABSPATH . 'wp-content/
to
WP_CONTENT_DIR . '/
This is because with 2.6 you can now move your content directory out of the WordPress install directory. In my config file, I've defined WP_CONTENT_DIR.
Maybe the plugin should be changed to detect if this constant has been defined.
Thanks.
