Laravel应用程序开发并上传到bluehost服务器[关闭]

I have been given a laravel chatting application which has been developed by another developer. I have uploaded it to blue-host server but many of the functionalities are not working, like email verification, invitation through email etc. I am confused if it needs extra configuration to get to work. Because i have just uploaded it like as we upload a normal site. This is the link you can check .

Looks like email related stuff is not working. There are settings for .env that are probably used by application to send emails. Edit them with your info.

Defaults are:

MAIL_DRIVER=smtp
MAIL_HOST=smtp.mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null
