Duplicate headers happen because we moved the title and context bar out of the package local master and to the
sitewide master. I think lars-blogger had been fixed but
I think photo-album might still be broken.
the way to fix it is make sure that you don't have
title and context_bar in the page or package local master
if you have one. I will check those two modules monday and
make sure they have been fixed.
the top of any package page (with a few exceptions) should
look like
<master>
<property name="title">@title@</property>
<property name="context">@context@</property>
Where context should be the list of lists as passed to
ad_context_bar.
You should not have title and context bar in you page and instead defer rendering of such persistent elements to the
sitewide master.
