The following hack allows you to enable or disable caching in all blogs without editing each blog by hands.
It took me a minute to enable cache on 120 blogs :)

Add this code to conf/hacks.php (create the file if it doesn't exist yet)

PHP

global $DB$Messages$cache_path
 
if( isset($_GET['enable_cache']) )
{                    
    $blog_array $DB->get_col'SELECT blog_ID FROM T_blogs' );
    
    foreach( $blog_array as $lbid )
    {
        // Update cache setting
        if( $cset_value $DB->get_var('SELECT cset_value
                                        FROM T_coll_settings
                                        WHERE cset_coll_ID = '.$DB->quote($lbid).'
                                        AND cset_name = "cache_enabled"') )
        {            
            if( $cset_value != && $DB->query'UPDATE T_coll_settings SET cset_value = 1
                             WHERE cset_coll_ID = '.$DB->quote($lbid).'
                             AND cset_name = "cache_enabled"' ) )
            {
                $Messages->add'Cache setting updated for blog #'.$lbid'success' );
            }
        }
        else
        {    // Create cache setting
            if( $DB->query'INSERT INTO T_coll_settings ( cset_coll_ID, cset_name, cset_value )
                             VALUES ( '.$DB->quote($lbid).', "cache_enabled", 1 )' ) )
            {
                $Messages->add'Cache enabled for blog #'.$lbid'success' );
            }
        }
        
        // Create cache directory
        mkdir_r$cache_path.'c'.$lbid.'/'NULL );
    }
}
