Issue with "Run Layout"

Hi All,

I appear to be having a problem with the "Run Layout" feature on the project I am currently working on. It opens up a web page and loads but the page stays white and will not load.

I was wondering if anyone else has this problem or knows why it is not loading?

Maybe the guide Troubleshooting Construct 2's preview server will help.

I have looked through this and nothing has seemed to work, I have also tried other projects and they do work. It only appears to be my main one.
