As a site-admin and space administrator it is possible to remove the page restrictions for a page, even though you don't have view or edit restrictions in that page.

When going to the space settings and into the 'Restricted Pages' tab, upon clicking on the padlock in the 'Operations' column for the restricted page, we get 'No permission You don't have permission to view this page' on for each padlock clicked.

It would be useful to improve the feedback/error message or implemented an easier way to remove the restrictions on the restricted pages list.

As workaround, the user can click on the padlock icon and ask it to open on a new tab, even though the message will display on the new tabs, and then refresh the restricted pages list to see if everything was removed for that page.
