Don't just overwrite your chyrp directory, set up a 'staging' area first, especially when the guy who writes chyrp assumes everyone will use git so he writes absolutely no 'safe upgrade' instructions for people using releases, nor "files that contain your config info so these are the most important". Good thing I backed up first :-
edit: also, copy over your .htaccess at the terminal
edit: ah, good, the staging area is broken. beautiful. and the developer thinks everybody's gonna have git so they can do a git pull on their webserver. Dreamhost survey sez...
[attila]$ git
-bash: git: command not found
