"Status" isn't updated.

I am trying out this convenient program for small business use. The problem I face is that the outbound fax "status" isn't updated. The "status" is kept in "Queued", but it has actually been sent.
I am afraid that I don't have coding skill and am waiting for a new release in which the problem might be fixed.
Another problem is that a pdf file cannot be sent, if portrait and landscape orientations are mixed in the pdf file. But I think this will be a limitation of Twilio's side.

I guess the problem will be caused by webhook service, because browser access to "http://(Server Address)/fax/twiml" and "http://(Server Address Here)/message/twiml" show "500 Internal Server Error".
And when I click "SMS Setting" in "Accounts" - "Account" menu, it shows "404 Not Found" page.
