Some are having trouble registering

I have had at least three people contact me that they are unable to register.  The first one told me that that the message stated that registration was closed.  I checked the form and the setting was wrong stopping registration too soon. 

The correction was made on Monday, but today I received two more saying:

Yes, please count me in . . .  as I go to requester (sic) online it says the site is no longer available but please get me registered .

I was able to go to the link, and register both with no difficulty.  I have received other registrations as well, who had no problem.

We apologize for the inconvenience caused. Can you please clarify if your users were still having the issue using your form https://form.jotform.us/WVjd5253/elkins

I did checked, but so far I could not find any issue with the form.

It can be submitted properly.

That is what I found when I submitted the information from those who emailed me with problems. For some reason, I had no problem but they did. I will let you know if I receive any more complaints of problems.

The only setting I see related to this error is that your form is set to disable after 46 submissions. According to your statistics you have currently used 20.

As my colleague mentioned earlier. Your form seems to be working fine. If you encounter any more issues please get straight back to us.
