[horde] horde 3.0.3 issue with arrays in registry.php

[frank at cyberbiz.ky]

Hi,

I tried to install Horde 3.0.3 on a Linux Server running fedora core 2, php
4.3.10, mysql 3.23.58 and apache 2.0.51

After uploading horde and imp to the server, configuring apache and running
it the first time, I got several PHP errors stating 'Illegal offset type in
...' most of them in registry.php - it seems to have its arrays within
another array. I was able to get rid of some of the errors. eg:

registry.php line 153ff:
$appName is still an array.
I added:
if (is_array($appName))
   $appName = $appName[0];
and it works.

any idea what the problem could be?

so long and TIA,
frank
