i have a custom master page layout. The problem is that it works great if i install it with the Web-interface or with SPD.. Unfortunately everytime i try to deploy it using VS either direct deployment or as a .wsp via powershell and activate it using SPD it says on the sp-site that this masterpage is not valid and i should choose another one.
Am i missing some information in the elements.xml or the feature?
little bit lost..
