Peer review plugin complains about the database needing to be upgraded, but trac-admin says the database is up to date

I installed the peer review plugin on a project and got it working with it, which involved running trac-admin.exe Y:/projectA upgrade on it. A few weeks later I wanted to use it on a separate project (Y:/projectB). So I enabled it in the admin -> plugins. It informed me that I needed to upgrade projectB. Running trac-admin Y:\projectB upgrade yielded the message "Database is up to date, no upgrade necessary". I am currently running Trac 0.12 dev - r7557 and traccodereview 2.0dev.

I think I have fixed it. It seems that if you install a plugin on one project it is visible to all projects (ie you can enable / disable parts of it for other projects), but it doesn't actually contain the plugin in all of the projects. After installing the code review egg into the project locally, I was able to upgrade the project and it seems to work now. Not sure if this is a defect or just part of how trac "works"

There are multiple ways to install Trac plugins. They can be installed locally or globally. See ​t:TracPlugins for more details. This could be an installation issue, or related to #4118.
