Issue Summary

When running under Node 14, the error message printed out when a second instance of Ghost is trying to bind to a port isn't the custom one we have, but the generic one.

1. Use Node 14
2. Run an instance of Ghost
3. Attempt to run another instance of Ghost on the same port
4. 💥

We have a check like error.errno === 'EADDRINUSE', which evals to `fa

Under the 'Theme' settings tab you can upload images. It would be great if vector images can be added so it can scale without causing artifacts.

But in the HTML output, it seems to be a date range instead:

• There seems to be a bug when navigating to the catch_all route but not contributors, ex. localhost:7878/test. The current implementation panics using both rocket and actix as server.
