[horde] Horde 2.2.5 problem

[tonyaccardo]

Hi all,

On a debian woody server, with php and pear upgraded (testing version
4.3.4), I've got this problem on the login screen:

Notice: Use of undefined constant SORTARRIVAL - assumed 'SORTARRIVAL' in

What is the problem? It was working fine, without upgrading php???

Best Regards.
