I am installed a SVN server (v1.6) on a VPS contracted with CentOS 5, Apache 2.2 with WHM panel.
I installed and configured all necessary modules and am able to create and access repositories via my web browser normally.

The problem: I can not commit or import anything, always return permission errors:

First error:

Can not open file '/var/www/svn/test/db/txn-current-lock': Permission denied

After fix the previous error:

Can't open '/var/www/svn/test/db/tempfile.tmp': Permission denied

And other... (and happends many others)

Can't open file '/var/www/svn/test/db/txn-protorevs/0-1m.rev': Permission denied

I've read and executed permissions on numerous tutorials regarding this errors, all without success. I've defined the owner as apache or nobody and different permissions for folders and files.
I'm using TortoiseSVN to connect to the server.

Some information that may find useful:

• I'm trying to perform commit through an external HTTP connection, like: svn commit http://example.com/svn/test
• SELinux is disabled. sestatus returns SELinux status: disabled
• Running the command to see the active processes of Apache, some processes are left with user/group "nobody". I tried changing the settings of Apache to not run with that user/group, but all my websites stopped working, returning this error:

Forbidden
You don't have permission to access / on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
