[rt-users] Page cannot be loaded error when Create/Update ticket

[Parani]

I am new to this RT,

I am facing problem when I am creating/Updating the ticket.
Issue :
       After entering details in the required fields, When I click the 
Create/Update Ticket. I am getting "Page cannot be loaded" error message.
If I refresh the page and entering the details again, I am able to save 
the changes.

Please help me resolve this.
