I recently upgraded from sharepoint 2010 to sharepoint 2013 and when I went and changed the default master page to my custom master page the gear icon and other items are missing. I'm a farm admin and have full permissions.
The thing is same custom master page worked in my previous test upgrade from sp2010 to sp2013. Any suggestions on why those are missing. When I change back to default out of box master page it shows up again.
Custom master page is deployed as wsp solution from visual studio.
