Thanks Edwin for the reply.
I have checked using hello.php . Symbolic link generated using hello.phph is working correctly.
I also tried by renaming htaccess.txt file , but no luck.
Do I need to set permissions for symblic links as well to 755, right now they are set to 777.
For the subdomain front end it just shows the site name.
this is the subdomain url - ultimateopenhouse.onsite2online.com
