I'm having troubles with Sellacious registration form.
Here is the link to my website (https://www.uniappunti.altervista.org/
). You can reach the Sellacious registration form by clicking on "Registrazione" button in top right position.
When an user try saving the informations entered, the following error appears (see Img1): "Error: Saving not allowed".
What could the problem be?
Img2 shows how the menu voice is set ("categoria visitatori is the client default category, I just renamed it).
Please let me know how to solve the problem
