I'm sorry for this newbie question, but I'M lost at this point:
I'm using Aquamacs 2.4 on MacOS X 10.6.8 and I'm currently trying to learn emacs and org-mode.
I have several *.org files containing TODO items and I was able to display an agenda for those files,
however suddenly (I must have changed a configuration, but I don't see what I did wrong) the "standard agenda" (with command "a") is completely empty:
There is only one line "Week-agenda (W06):" nothing else.
However, all org-files are in the agenda file list and if I open one file and choose Set Restriction Lock to the current subtree, the rebuilt agenda view gets populated with the items from that subtree. But without the restriction I get an empty agenda again.
How can I switch back to the configuration I had before? Any ideas what I might have done wrong?
btw: when I invoke the agenda with option "t" (list of all todo entries) it seems to work and I really get this list.
EDIT
some more information: it seems to happen when I load my whole org-files directory as "agenda files". Something in there seems to change the agenda configuration. I'll try to add the files one by one and see when it happens.
