Ok I use this site called edmodo.com and it used to work perfectly fine but one day after I login and get through the main page it shows nothing. Just blank. Any idea what happened I noticed this first in Konqueror and then on Rekonq. But this strangely works fine in Google Chrome. Also when I preview in Webkit in Konqueror it saysThe specified file or folder /home does not exist. even though it says in the bar https://www.edmodo.com/home

Can you please try to reproduce under a new user?

does it work if you change the browser id? wrench -> tools -> browser identification ->
