It's not compatible with Trac 1.2+. Code needs to be migrated.

[Jun Omae]

That is a duplicate of #13563. The issue has been fixed. Try to upgrade to the latest version.

[Ryan J Ollos]

You are right, thanks. I just looked at the tags on the project page, which hadn't been properly updated to list 1.2.

I installed the latest version and this problem exist.

[Jun Omae]

No get_db_cnx is used in the latest version. The same error shouldn't be raised. Your upgrade steps have something wrong.
