 * My server error log has thousands upon thousands of entries for the following
   error message:
 * [10-Mar-2012 00:22:41] PHP Fatal error: Call to undefined function w3_url_format()
   in /home/fontlife/public_html/wp-content/plugins/w3-total-cache/lib/W3/Plugin/
   PgCacheAdmin.php on line 213
 * I think I fixed the roblem by adding the following line to the top of the PgCacheAdmin.
   php file:
 * require_once W3TC_INC_DIR . ‘/functions/url.php’;
 * The function w3_url_format seems to be defined there.
