After perusing the comments above, in particular Isaiah’s (@adeptec’s) comment, I reviewed my other plug-ins. I had a password protection plug-in activated, though the password protection was no longer enabled, when I began having this problem. I deactivated the plug-in and then completed and submitted the form in various browsers and it wasn’t working before, but is for me. I have a collection of people who should test it for me in the next few days. If I don’t do any updates, then assume this worked, and then I would suggest that you go through other of your plug-ins and see if there is one that may be affecting this one. If it’s not necessary, as mine no longer was, deactivate and see if it makes a difference.
Hope this is able to help at least one someone!
