[trean] Fatal error

[Nusa]

Hi,

I'm installed horde 2.2, imp, forwards and kronolith. It's OK. I want
install trean, I modify 'horde/config/registry.php', it's OK, my icon is
present in IMP but when I want to go in trean  I've got this error message :

Fatal error: Failed opening required
'/var/www/html/horde/trean/../lib/Test.php'
(include_path='.:/usr/share/pear') in /var/www/html/horde/trean/index.php on
line 13

Test.php doesn't exist,  it's a copy of Trean.php???

Can you help me please?

Charles
