I am looking for the administration menu to add fields in my project cause i am encountering issue to do it from the section fields in the project. When i click on add a new personalized field, i get an error. I see the field in the pramaeters but not in the project.
So basically i am stuck at the first step of this tuto :/ ... I am looking for hours now this admin menu..
If someone can give me the way to go there that will be great !
