Custom fields missing on the backend

Well I just tested your code locally and it works (make sure to use text as the field_type and not Text). Can you see any custom fields at all?

Hi, sorry for the delay.
Changing Text with text in the field type has been succesful and now I see the custom field on the ticket backends side.

The problem still is present with the “upload field”. I can upload the file in the frontend but it doesn’t display in the backend.
I’ve also checked the “wordpress write permissions” and it is ok.
WP and Plugin is the latest version avaiable.
What can i do?

Could you please paste the system status report here.

Here is the status report:
