FYI: the timeout seems to be occurring when I specify a Branch on the +addseries page that did not yet exist. (I presumed that doing this would register the branch.)
I was able to successfully create two series by (a) not specifying a branch at all, and then (b) specifying a branch that did exist.
Perhaps specifying a non-existent branch is a user error, but clearly a generic timeout message won't help said user diagnose the problem...
