5.0.5 beta apache not working

After I updated the 4.x version to 5.0.5 beta, apache stopped to work, I cannot start again.
Could anyone help me, please?

Command line:
service httpd restart

Starting httpd: Syntax error on line 1 of /etc/httpd/conf.d/namevirtualhost.conf:
The address or port is invalid [FAILED]

/etc/httpd/conf.d/namevirtualhost.conf content

Server. OpenVZ VPS
OS: Centos 5.x 86_32

Can anybody help me?

Have you tried rebooting the server?
YOu should also send a support ticket to Interworx, since that’s the fastes way to get support.
