Simple email form stopped working

I have two web pages both on 2.9. Both have simple email comment forms. One of them stopped working for no apparent reason. I have checked the html on both working and non-working pages and they appear identical. It seems the from address is getting lost. I have even upgraded to the latest contao in a test bed, but the same error keeps occuring.

The error I'm getting is below. Any idea what I can look at next? FYI: The broken contact page is at http://www.theaterwerk-bodensee.de/contact.html

Any ideas what I can look at next?

Code:

Hello,

this usually happens when the email address is empty. Please check in the settings and in the root element for that web page if the email address is set properly.

BTW: As German speaking person I recommend to post your questions to www.contao-community.de.

Thanks. Actually, I had checked that and it was set in the form and correctly tagged. It was the system admin email that was blank.... which shouldn't have happened since you can't submit a blank. I guess my database hickuped.

I posted here: viewtopic.php?f=4&t=3600

Since the original post wasn't approved, I couldn't reply directly and didn't want people looking into this when it was solved.

Thanks,

Allen
(Thanks for the info on the .de forums.... I actually browse both. I tend to end up here more often because German is my second language and my google-foo tends to be englishish).
