I'm having the same issue as ThomasBDay, all i get when I open designer

I'm having the same issue as ThomasBDay, all i get when I open designer is choices of Palette, Themes and Custom. There's no option for me to change layout to legacy as was suggested in response to ThomasBDay's question.

I have checked your account and the option is now called "All questions in one page" which is the same as the legacy layout, please go to your form settings and follow the steps provided by my colleague on the other thread: https://www.jotform.com/answers/1265360 

I hope this helps.
