See this issue which I created a few months ago because I have no knowledge about installation so you can check This I am not sure that is your solution is there or not but just check it
There are a lot of reasons the page might be blank. What errors do you see in the Network tab of your browser dev tools? Do you see any error messages in the console? Do you see any error messages in the various server logs? What’s the output of netstat -ntlp?
Do you have Apache acting as a reverse proxy? If not, that would likely explain why you're just seeing a blank screen. If you are, you may want to look at the apache error logs.
If you want something simpler, try stopping apache and then restarting your dev server. Note that the dev_server.sh has no security, so you'll want to take that into consideration if you're running it directly on port 80.
