SERVER ERROR ( FOR BIDDEN)

[cloudselvam]

Hi,
  I have installed vesta CP on centos 6.4 .

In the Round Cube Mail I'm getting the following error.

"SERVER ERROR ( FOR BIDDEN)"

In the roundcube server  log

"PHP Error: Error loading template for logout in /usr/share/roundcubemail/program/include/rcmail_output_html.php "


Round cube version :

roundcubemail-1.0.5-1.el6.remi.noarch

   has been installed on the server.

Please help me to resolve this issue.

Thank You.

Regards,
