What version are you running?
ReviewBoard 2.5
What's the URL of the page containing the problem?
There are two problems but they seem related. The first is when trying to add a new repository, the second is when attempting to post a review. I do want to point out that this is running in a docker container. On the first execution (ie. docker run'ing all images) everything works but on subsequent start's I receive these errors.

Trying to add new repository (http://cr/admin/db/scmtools/repository/add/)
rbt post

What steps will reproduce the problem?

Trying to post a diff
