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.
Could you please give us the link to the exact page where the jotform is found on?
I believe that there is a conflict and when I took a look at your other threads I found this page:
Where there is a conflict with the form and the code on your website.
To fix this, please use the iframe embed code instead: How to get the jotform iFrame Code
Once you do that issue will be resolved.
This is the link to the (now old) thread: http://www.jotform.com/answers/393825-Das-Formular-wird-nicht-vollst-ndig-bermittelt-angezeigt-Beispiel-Feld-Montage- where I found the page.
Do note that since a conflict is being shown on that page, you should use iframe embed option on all of your pages as they too would not be loaded properly due to the JS conflict.
