A few months ago I was working on a test GAE app. I was able to start the launcher and open the browser both on the app port and on the SDK Console port, and they both were working well.
Then I installed CherryPy, I created a CherryPy app, and I was able to browse to the app.
Today I restarted the GAE launcher. When I browse to my app page everything works well, while browsing to the SDK Console it shows the correct content, but doesn't show the static files.
The log mentions CherryPy.
- Is the CherryPy I installed conflicting with GAE?
- Does GAE use CherryPy (and my installation has nothing to do with it)?
- How do I fix it?
For example when I browse to http://localhost:8002/assets/common.css (which is the css used by the SDK Console) I get the following log:
