I found out why it was cutting off the button…they width of the from needed to be increased. Because I had a sidebar, it was resizing the form and making it too narrow. I added a <div style=”margin-left:-80px”> to move the form to the left a little and it now shows the button in full. This might not work for others, but helped me!
Mine too is having problems with the Submit Form button.
It is horizontal, but is being cut off so that I can’t see the full button. It only says: Submit Fo
