After we did a migration to a portal we found a weird behavior which I need your help in we migrated the masterpages manually and added the ribbon code and all of the placeholders
the issue is that when a page is checked out to another user the ribbon tabs (Browse,page,publish) aren't displayed and when you click on the edit page icon it just refreshes and nothing happens
there's is no tabs to select to override check out, also there's even no status message to tell the user that the page is checked out to another user
I have a feeling that I forgot a placeholder or something in the master page which is responsible of this behavior
So please help Thanks.
