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.
I think we still have an existing issue with our oEmbed plugin. If you will check your browser console, you'll find an error that is causing this.
I have forwarded this to our developers. If there are updates, you should know it through this thread.
For now, please use our Embed Form plugin: https://wordpress.org/plugins/embed-form/. Or, simply embed your form using one of our embedding methods. I would recommend the iframe: https://www.jotform.com/help/148-Getting-the-Form-iFrame-Code.
