Roundcube require error gives blank page

[flosoft]

Hey,

I get this error in my logs.
[20-Jan-2008 13:25:06] PHP Fatal error: require_once() [function.require]: Failed opening required 'include/rcube_shared.inc' (include_path='.:.:.:') in /var/www/vhosts/flosoft.biz/httpsdocs/svn/roundcubemail/index.php on line 81

It gives me a blank page. But when I refresh often enough, I get the login screen. Any idea on how to fix this?

Sounds like sometimes RoundCube can't set the include_path. Since you didn't say much more, this is hard to debug. I am guessing though that this is your environment (buggy PHP version).

I have the same problem. previous versions of RCM have worked flawlessly on the same setup. previously I have just upgraded directly via svn and then used the info in UPGRADE doc to see which configs to change. This time I did an upgrade with svn and then used the installer to create/update the main.inc.php etc. Now I get the blank page.
It could be related to the PHP version 5.2.5-3 (debian linux server) I am running but I cant see why that should have any impact (it has however been upgraded recently).
