Try this it fixed the problem for me
Redo the upgrade via Tools->Upgrade->Re-install automatically, then clearing the browser cache.
All fixed and working again. This thread has more options as well

I have the same issue as you – the blog works OK but the add post page buttons are gone.
Have cleared the cache in my browser, tried it in Safari and Firefox and have deactivated all the plugins – no joy so far
Any suggestions appreciated
Thanks
Ross
