I found this is in 2columns-right.phtml.
I found what I think was a corresponding line in main.xml, but can’t for the life of me figure out what file that is calling. I’ve dug all over the admin section and can’t see anywhere you’d set “global messages” from the admin interface.
<!-- [start] global messages -->
<!-- [end] global messages -->
Did I just happen to choose something that’s not yet implemented? I tried creating the file frontend//default/default/template/core/messages.phtml and editing main.xml to change:
<block type="core/messages" name="global_messages" as="global_messages"/>
<block type="core/messages" name="global_messages" as="global_messages" template="core/messages/messages.phtml"/>
That didn’t seem to do anything either.
