[Plugin: WP Super Cache] PHP notice: Undefined variable: php_fd

  • I have several blogs on the same VPS server (all WP 3.0.4 and Supercache 0.9.9.8)

    As of a couple of days ago, I noticed the following error in the error_log (of all blogs):

    PHP Notice: Undefined variable: php_fd in /wp-content/plugins/wp-super-cache/wp-cache-phase2.php on line 572

    Anything serious? Can I do anything to avoid it?

    thanks,

    Peter
