Virtual Host Template Issues

[robfrew]

I am trying to use the PHP_SUEXEC VH Template, however, when I add the domain and click save, I get a blank white screen.

I check the log and see:

Call to undefined method: dtbldef->add_() in /opt/lsws/admin/html.4.0.7/classes/ws/DTblDef.php on line 30

This is with version 4.0.7.
