Indexhibit Support

I have a problem with the settings of the exhibits, disappeared on "Post-Nav Text", the button "Update" and the "Sections", "Edit Notions", "Edit documentary"
and "Create New Section"

I tried reinstalling and still gives me the same problem, thanks for the help

I'm sorry, I don't quite understand the question - can you rephrase this?

thank you very much for the reply, but I could solve
