RTIR Create incident

I’ve just installed RTIR and cannot seem to get past this problem.

If a new incident report is mailed or created, I open it and then click
the “New” link under “The Basics” to create an incident from this
I fill in pertinent information and click “Create” but nothing happens.
On a few occasions it did work, but I can not figure out what was
different for it to work. I checked perms and the Duty Team has all
rights, my user account is super user. I checked queue perms and my user
account has full perms.

What am I missing? Anyone else have similar problems?

RT works perfectly, no issues that I can find.

RT 3.0.5
RTIR 1.0
Perl 5.8
