I've made some changes on my local machine to my app to how a matplotlib graphics is displayed. I'm happy the results, checked in the changes to GitHub then did a git pull to a directory on PA and restarted the server. Different results.
I switched directories to a place where an exact version of the same app is running on PA did the git pull, server restart and viola' the changes appear. Is there some PA magic that I don't understand at play here?
