Roundcube error 500

hey guys,
I've recently ported from SME Server to ubuntu, and installed Ispconfig 3 following the tutorial for the Perfect Server... All worked out perfectly untill i wanted to update and keep squirrelmail to roundcube. Followed the tutorial all worked good for the main domain, but, when i try to add a secondary one in ISPconfig, when i check try to access the domains webmail, it says error 500

Now the config : /etc/apache2/conf.d/roundcube.conf

Code:

Alias /webmail /var/www/webmail
<Directory /var/www/webmail>
  Options +FollowSymLinks Indexes
  # This is needed to parse /var/www/webmail/.htaccess. See its
  # content before setting AllowOverride to None.
  AllowOverride All
  order allow,deny
  allow from all
</Directory>
# Protecting basic directories:
<Directory /var/www/webmail/config>
        Options -FollowSymLinks
        AllowOverride None
</Directory>
<Directory /var/www/webmail/temp>
        Options -FollowSymLinks
        AllowOverride None
        Order allow,deny
        Deny from all
</Directory>
<Directory /var/www/webmail/logs>
        Options -FollowSymLinks
        AllowOverride None
        Order allow,deny
        Deny from all
</Directory>

The outcome of the error log from /var/log/isconfig/httpd/www.domain2.com/error.log

Code:

[Fri Dec 21 12:16:21 2012] [error] [client xxx.xxx.xxx.xxx] SoftException in Application.cpp:221: File "/var/www/webmail/index.php" is not in document root of Vhost "/var/www/amcinromania.ro/web"
[Fri Dec 21 12:16:21 2012] [error] [client xxx.xxx.xxx.xxx] Premature end of script headers: index.php

So from this, i get it is not the docroot... but then why does the alias is for ?
Also if i try to take a look at other configs... just to copy paste the redirect code, the manual ( the apache one ) works perfectly on both domains meening www.domain.com/manual and www.domain2.com/manual .
Also the squirrel works well too... why ??? The config is almost the same !!!

Thanks ppl

 

Do you use SuExec or suPHP? If so, please disable it/use another PHP mode.

 

thanks and sry for the late reply, i was on a lil bit gone for these holidays.

I use suexec of course but for the other domains not for roundcube config...
Now the idea is why does it work on the primary domain that uses as suexecusergroup web1 client1 and not for the second domain, web2 client2
How can i make it work on both domains... with the respective simlinks / aliases
thanks

 

Niiiiiiice, thanks guys, it worked, can be closed and marked as solved,
P.S. For those who will read this, everything works perfectly on a Ubuntu Server 12.10 and Roundcube ver 0.8.4, and squirrelmail included.
