New Post: Documents upload doen't work with manager users

Dear All,
I have two users in my nbstore: an Administrator user and a Manager user.

If I upload the documents on catalogue items with the Administrator user everything works, but If I try with the manager user, I can upload image, change everything but the documents can't be upload.

There aren’t specifics error, simply no documents are upload on “productdocs” folder.

Any idea? I'm using DNN 07.03.01 (20) with NBstore 2.3.8.

Thank you very much for your help
Alessandro
