Well, more weirdness. When I went back to the survey creation interface, I used the same survey name as the one that “didn’t save,” and it said a survey with that name already exists. I opened the “Survey Results” tab, and low and behold, there it was!
It seems that if, after getting the error message, you leave the plug-in interface, your save completes.
This is a REALLY easy-to-use plug-in. I’m new to creating web sites with WordPress – this is just my second site and is much more complex and functional than my first one was. http;//www.watsonvilledrycleaners.com/wdc if you care to have a look. There will be a survey posted there in a couple of minutes!
Thanks for the great work, and the helpfulness!
