I am the owner of an SP online site and the permissions tab has been disabled for me. enter image description here

Url of the above page is:

https://Tenant.sharepoint.com/sites/SiteName/_layouts/15/user.aspx?obj=%7BIDDDDDD%7D,list&List=%7BIDDDDDD%7D

but I can still add users to the documnet library through the right-hand side menu as shown below:

I do not know how this has happened or how to fix the issue.

It seems that I can manage the groups in SP designer 2013 as well enter image description here

Can it be due to ShortPoint SPFx? it seems I cannot remove it as there is no remove button for it: enter image description here

  • Is the URL of the page shown in your screenshot https://<siteurl>/_layouts/15/user.aspx ?

    From the given URL: Tenant.sharepoint.com/sites/SiteName/_layouts/15/…, is it the permission page of a list? And from the screenshot, it seems that you have stopped inheriting permissions in the list, right? Do you have appropriate permission to the lsit? Also change a browser to have a try.

  • It is the permission of a list, I have also tried Edge and Chrome, it did not work in any of them, everything was fine, but not sure what has happened that caused the tab to be disabled, it has happened today. Yes, I stopped inheriting permission while the tab was working about a month ago, but the tab was working until yesterday.

  • It also solved the problem of showing the "remove" button for removing Shortpoint SPFx
