[horde] Blank Page with trean

Wed Feb 13 13:29:21 UTC 2013

Hi,

trying to add a bookmark in trean (which I've never used before) is  
resulting in an empty page. Apache error_log is complaining:

[Wed Feb 13 14:11:51 2013] [error] [client 193.227.144.90] PHP Fatal  
error:  Class 'Horde_Queue_Storage_Array' not found in  
/usr/share/php5/PEAR/Horde/Core/Factory/QueueStorage.php on line 10,  
referer: https://mail.bruecko.de/horde/trean/

Any advice?

Regards Hanns
