What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Sorry for the inconvenience. We currently don't have any reported issues about our servers. The Form Builder have an auto-save function as well. Can you please try using the Form Revision History Tool and verify if you can still recover the updates you made. Here's a guide: How-to-view-form-revision-history
Normally, the Save function will not work properly if you have a problem with your internet connection. It can also happen if you are not logged in to your JotForm account. Lastly, please make sure to open the Form Builder only in 1 browser tab. The reason is because the changes you made in the form will be overwrite by the other Form Builder due to the auto-save function.
Hope that helps. If you have any questions, let us know. Thank you.
