Did upgrade Ingo and Horde to 3.1.1 and 5.1.1. I did upgrade the  
backends.local.php to read:

<?php
$backends['imap']['disabled'] = true;
$backends['sieve']['disabled'] = false;
$backends['sieve']['script'][Ingo::RULE_ALL]['params']['utf8'] = true;
?>

but the horde error log still does complain:

supplied for foreach() [pid 24197 on line 116 of

The rules itself are stored and configured in the standard sql backend  
configured since initial installation of this instance.

Did a "grep \'script\'" in the ingo config folder but all 'script'  
matches are arrays.

backends.local.php:$backends['sieve']['script'][Ingo::RULE_ALL]['params']['utf8'] =  
true;
backends.php: *  
$backends['sieve']['script'][Ingo::RULE_ALL]['params']['utf8'] = true;
backends.php:    'script' => array(
backends.php:    'script' => array(
backends.php:    'script' => array(

backends.php:    'script' => array(
backends.php:    'script' => array(
backends.php:    'script' => array(
prefs.php:$prefGroups['script'] = array(

Whats wrong here? Something i can do to get Ingo working again?

PHP version used is: 5.3.2-1ubuntu4.19 from Ubuntu LTS 10.04 Server variant.
