For many people, it seems (you and I included), Page Titles are the same as Article Titles because of Rule 2 here:DrDigital wrote:...and went and had everyone that has access to just go in and manually change every single article in the system to get ride of the double content titles and in an hour or two we would have the entire site redone. Vs a 20 second fix

If this is the case for you, then changing the global parameters to turn off Article Titles might work as a quick fix. This was also my initial reaction to the problem, but then I realized that for some menu types, such as Category List Layouts, you're left without any links to articles because the article titles have all disappeared.
