Can you please share a screenshot of how you have added the Form with the Oxygen page builder? Did you use the FluentForms module in Oxygen or a shortcode module to add the Form?
Hello
I have the same problem. Before updating to Oxygen 4.0 it worked fine, now the forms don’t show up anymore, also if i place them again or try to place a new one …
This only happens using the module. If i use the shortcode it works, but i need the ability to edit the form in the module …
Thanks!
