Steps to reproduce:
- For a WordPress.com Simple site, go to My Sites > Site > Media.
- Add items until you run out of space.
- Upload a new item that exceeds the site storage limit.
- Observe the error message that appears.
Result: I expected to see a warning about going over storage capacity, but I see a generic error instead. (11m58s)
