On the accounts page I expect to see a Documents subpanel but I don’t. I do see the many to many relationship between documents and accounts. On the document page I do see an accounts subpanel.
I am running 7.11.1
I don’t see the documents subpanel in the studio accounts subpanels section.
First, try a Admin / Repair / Repair relationships, and QR & R.
If that doesn’t work, here are a couple more suggestions…
See if you disabled it via Security Groups / Roles
See if you renamed it to something else (through code, or through Admin / Rename modules). If you go to the Accounts detail view, and open your browser’s developer console, and check the page source, search for an element with id “whole_subpanel_documents”. If it’s there, that is the Documents subpanel. But maybe it is hidden, or shown with a different name to the user?
Where are you seeing that? In Studio, or in PHP files?
There seems to be something unhealthy about your system, maybe some old customizations that are breaking your system? Maybe if you examine the relevant parts of your “custom” directory you might find something.
