I made a copy of my v4.master, changed the PermissionsString for idNavLinkViewAll to hide the "All Site Content" link, and changed the width of the Quick Links list from the default 150px to 250px. I then saved the copy, checked it back in, published it, approved the changes, and set it as the site default master.
However, when I open the site's home page none of the changes I made in the master are in effect - nothing has changed. All users can still see "All Site Content" and the width of the quick link list is still 150px.
Any suggestions would be appreciated.
