roundcube - error during add delegation

[Jan Kowalsky]

Hi all,

with 3.1 on debian 7.0 I try in roundcube to get the delegation-plugin work.

With debugging enabled in /var/log/roundcubemail/errors I get:

[18-Nov-2013 14:55:19,000000 +0100]: PHP Error: Failed to load plugin file

in roundcubemail-web-interface I only see "an error occured".

Who else tried this plugin in debian - even with success?

Thanks and regards

Jan
