No visual display

Hi, I’m having this problem with the visual display on the left, showing only a grey box.
Can anyone offer any assistance with this?


To add on, I’m using Google Chrome.


Hi Parkel,

Did you try to refresh the page? does it happen every time?

btw what is your chrome version? do you have errors in developers console ? (F12)


I tried refreshing the page multiple times already. No luck there.
My chrome version is 40.0.2214.115 m

There are errors and warnings in the console though:

I have also tried disabling adblock plus, still no luck.


Are you behind your company’s proxy?
It seems that something removes the ‘Access-Control-Allow-Origin’ header!
(btw it also blocks websockets)

Can you check again after cleaning your cache?
