Hi, after upgrading the whole Horde installation to the newest version, _lots_ of these error messages are appearing in log file: 2011-04-27T20:39:12+02:00 WARN: HORDE [turba] PHP ERROR: Invalid argument supplied for foreach() [pid 7648 on line 149 o f "/usr/share/horde/turba/lib/Turba.php"] Any ideas ? Thanks. azur
