[horde] Problem with installation and test page in Horde RC1

[Alex Gavrila]

First of all, I have horde 2.2.1 and IMP 3.2.1 installed and perfectly 
working. I want to test the new version on the same server, for now in 
paralel. Old horde is installed in /horde (on the webserver) and the new 
Horde is on /horde3

I just installed RC1 and after all the steps in install, the test page shows 
absolutely nothing! Just a blank page. If I copy the test.php from horde 
2.2.1, in /horde3, the page works correctly, identifying horde RC1 and IMP 
RC1... But with the test.php from RC1, the returned page is empty.

Did I miss something? Or is not possible to have 2 different versions on the 
same server? For now, I want to keep the old version and to test the new 
one...

Greets,
Alex.
