I thought I was getting closer to figuring it out today, but it is
weird. Using the gem on one machine I don’t get it, on another I do.
When I get a chance, I will look further into just what the
differences are.
For now, I just do it without the admin and change the few things
that need it by hand…
I have yet to reproduce this error; like you say, there must be some
difference between the two setups. Of course, it’s been my opinion for
a while that having the /admin namespace is not necessary in an
extension since you can define the route prefix. To each his own.
