W3TC empty page cache message always on when activating wpbruiser

Hi,

when I activate WPBruiser, W3TC message “one or more plugins have been activated or deactivated, plealse empty the page cache…” appears and won’t go away. No matter how many times I empty the cache page, empty all cache or try to hide the message, it won’t go away.

Hope someone can shed some light.

Thank you!
