I prepared a new page with Page Builder and inside I prepared a form builder. I have a lot of problems with it. The page is here: https://www.rules-chess-strategies.com/el/programma-proponiseon-skaki
I readed your documentation here: https://www.joomshaper.com/documentation/sp-page-builder/form-builder
I prepared a small video 1-2 minutes long. It called “Form Builder Error”.
Please check the phone; I forgot to mentioned it during the video. On phone for example I can add anything I want, for example a text like “test”. I'm giving the link below.
