Hi @sebastopolys , thanks for the quick response.
Link:
The fields are “Codigo Postal” at both sections “Datos alumno” and “Datos Empresas”.
Other custom fields are: “NIF/CIF” and the “Bonificar formacion”.
When somebody writes there, the plugin did not keep that information and if i want to put it manually when i click at the save button (admin panel) the text disapears…
I tried creating a new custom field and it happens the same.
Regards,
Jordi
