I pushed a new version of my website, but now the CSS and static images are not deploying properly.
Here is the messed up page: http://www.gaiagps.com
Appeng
I had this problem as well. I was using flask with GAE so I didn't have a static handler in my app.yaml. When I added it, the deploy works. Try adding something like this
handlers:
- url: /static
static_dir: static
to your app.yaml and deploy again. It worked for me. Apparently Google is trying to optimize by not updating files that it thinks users can't see.
