I recently tried to upgrade blog module using following process

1. changed old folder name on server from "blog" to "blog_old"

2. Uploaded new blog software to folder "blog"

3. tried it out and nothing happened then realised i probably needed to upgrade silverstripe version first

4. deleted folder "blog"

5. renamed folder "blog_old" to "blog"

6. Chaos - get website error and can not login as admin

Changed my config to include " Director::set_environment_type("dev"); "

and get following info

Any help appreciated
