I don't know what to do anymore.
Please help, work according to this procedure:
https://learn.getgrav.org/17/admin-panel/extending
My goal is this, nothing more:
https://learn.getgrav.org/user/pages/05.admin-panel/08.extending/myPage-customField.jpg
I created page.html.twig with the settings according to the instructions, then in the blueprint folder I created page.yaml again with the appropriate content to add a field: New Text Field
And I can't get the new field to be added.
I also tried to implement the whole process only in the file item.html.twig and therefore item.yaml, but the result is the same, the field is not displayed in the administration when creating a new page as an item.
Please what am I doing wrong? Is there anything else that needs to be implemented?
Thank you for your help.
