PHP development workspace preview not working?

When I go to launch my workspace in the browser I get a blank page with nothing on it. Could someone explain why this is happening please?

I am having the same problem with the same course. It started on Saturday morning for me. I contacted support just now so hopefully they can resolve it quickly.

Hi Stephanie,

I was having the same problem as you and I contacted support. I was told that it was my code that was causing the problems, and to paste my code in the forums for them to address. They wanted it in the forums in case others had problems, and since you already had this post started, I figured I would add it here. This was their last reply:

"Hi Juan,

Thanks for getting back to me! I've just checked in with our developers, and it's actually your code that's causing the issue. Please post this with your code on the Forum. Once you've posted this, our teachers can then provide assistance once they've returned to the offices. We aim to address most questions such as this on our forum so that others who may have similar issues can see it posted there and save them the time of awaiting a reply from one of our teachers.

Please let us know if you have any additional questions about this! "
