Q: There was an error when I ran "vagrant up". The configuration didn't seem to be recognised properly. When I read the homestead documentation, the command to run is "homestead up". It's fine now.
A: You may use both in older versions of Homestead/Laravel. Unfortunately, the vagrant up command may not work properly in the newer versions.
Q: I see a blank page when visiting Laravel, I'm using Homestead.
A: You need to fix permissions on the Code folder if you made it with the sudo command.
