A question I see a lot and one that confused me for a long time!
Basically, your laptop comes with a lot of setup you forget is there. The server needs the same dependencies, environment variables and permissions that aren't necessarily available on a server
Check the error logs first they usually tell you what’s missing
Can I ask a DUMB programming question?
If my app works on my laptop, why does it break on the server?
Is it the code, or is it something I forgot to copy?
