Steps to recreate

1 - Log into backend as administrator

2 - Choose a content node, right click, choose "Role based protection"

3 - Pick a role who will have access to this page

4 - In the "Login Page" or "Error Page" click "Choose"

PROBLEM: The dialog to pick the login and error pages doesn't appear. Delete also does nothing. However the "Remove protection" button does work.

Troubleshooting and other comments:

• Upgraded from 7.40 ->7.43

• Deleted /App_Data/umbraco.config and restarted web site

• Republished whole site
• Attempted to confirm my admin "User Permissions" but "Select pages to modify their permissions" list is blank.
• Tried all of the above as different administrator and saw same behavior.
• Database on host is Mircosoft SQL Server 2014. This is the staging environment. I frequently backup my live site (Mircosoft SQL Server 2012) to the staging site.

• If a member has the requirements, he is assigned to the role that has access to this content:

  var result = ApplicationContext.Current.Services.MemberService.FindMembersInRole("Member Access Group", member.Username).Any();
  

  • Confirmed with hosting environment full permissions for all folders "IUSR", "IIS_IUSRS", "NETWORK SERVICE"

Anything that can be suggested would be greatly appreciated.

Thank You
