The user has access to the post in the frontend and can even open the editor. In this editor, however, he cannot edit any data. The cursor is not active.

Details:
• I set up JCE Editor Pro.
• I have assigned the group "Author Group Velo" to the user. The parent group is "Author group" --> and there the parent group is "Editor"
• The access level is "GBlog Velo" she has access to "Author Group Velo"
• The content category is "G_Blog" --> Edit allowed, Edit status allowed, Edit own content allowed
• "G_Blog" is entered in the post under category.

What am I doing wrong why can't he edit the post. Who can help me?

Many Thanks
That was the right tip!
I only have to register the "author group" in my profile "Fontend Autor Gruppe". Then everything worked!

PS: I have JCE Pro 2.9.23
