I have created a form that originally redirected to a confirmation page. After entering a test entry, in preview mode it worked fine. On the actual page, however, it doesn't; it returns a blank page. I removed the redirect and substituted a text response. A test entry with that configuration returned a blank page with just the text at the top.
I have several (20-30) forms on other pages that work just fine. What could be the problem with this one? And, yes, I've tried turning off all extensions without any change of result. I don't think it's a plug-in conflict since every other form works perfectly.
Can you help me?
Here's the page with the form:
