Virtuemart "Send Your Question" button not working

When I click on "Ask a Question About This Product" on the Product Detail page of my site (using the Furniture Store template), I can complete the form but when I click on the "Send Your Question" button, I get the following error:

500 - Layout default not found

And the email never gets sent. I've attached the screen print of this error.

Please let me know how to get this working.

Thanks!

can we see your site ?

The production site doesn't have the issue (I removed the "Ask a question about this product" button on the production version of the website so that users don't encounter the issue). The URL for the prod site is www.paulmullenfinewoodworking.com .

The issue only happens on my local machine at the moment. I can provide you with the url for that version, but don't want to post that link on the forum. Is there a way I could send it to you privately?

If not, could you tell me what to look for myself so I could try to get it fixed?

Thanks!
