Hello, I have the same issue. Working away on Pages when suddenly the preview & save buttons disappeared. I am on 3.01 and I have disabled all plug-ins, changed to the default theme (we have a custom one) and switched back and forth between 1 column and 2. Still no buttons. Since I did not add any plug-ins or change my theme or my columns – I wasn’t sure why those would affect it anyway. This seems to be a known and recurring problem from all the entries I have read and all the feedback seems to be that deactivating plug-ins and changing themes has not helped. A couple of people have claimed that the buttons came back with changing the columns but most that were successful in getting them back really have no idea as to what actually worked. Has anyone come up with a definitive answer or at least some addition steps to try?
