@kzidane

I am not sure what happened, but it seemed to have been fixed. But now there are a lot of new errors in the console:

@SNathJr do you happen to have adblockers installed or third-party cookies disabled?

SNathJr commented 5 years ago

@kzidane No I do not have third party cookies disabled

I also have disabled all browser extensions

kzidane commented 5 years ago

@SNathJr do you have another AWS Console session by chance?

SNathJr commented 5 years ago

@kzidane No, I do not have another console, however I sometimes use an offline version of CS50 ide running inside WSL (Windows Subsystem for Linux)

kzidane commented 5 years ago

@SNathJr if you try the latest version of Firefox, do you get the same issue?

SNathJr commented 5 years ago

@kzidane On the latest version of Firefox there are a few XML errors:

XML Parsing Error: no root element found
Location: https://vfs.cloud9.us-west-2.amazonaws.com/vfs/d9xxxxxx26xxxxxx810xxxxxxxx16xx/environment/_/_/tab0

Also there are errors like that of Chrome:

kzidane commented 5 years ago

@SNathJr this sounds like the doing of some sort of adblocker. Are you absolutely sure you don't have any adblockers enabled on this machine? Can you try from a different machine by chance?

SNathJr commented 5 years ago

@kzidane I am absolutely sure that there are no ad blockers on my machine (other than default windows firewall of course). Also, I am getting similar errors on a mac book (chrome) and a linux (firefox). Then I thought may be my ISP is the issue, so I tried with a different internet connection, but still the similar errors appeared.

SNathJr commented 5 years ago

@kzidane This issue appeared again in my CS50 IDE.

SNathJr commented 5 years ago

@kzidane I reloaded the page, with only the base URL (https://ide.cs50.io) and this happened:

SNathJr commented 5 years ago

@kzidane I deleted all my browser history and cookies and tried again. And this time it took me to my workspace smoothly.

I was just thinking, is it possible that all these issues are coming up because of old session cookies (as the next time you login to your ide your session and instance would both change, causing some conflict)? If this is the cause, how about deleting old cookies and creating new ones, every time a user logs in (given the old session is expired).

kzidane commented 5 years ago

@SNathJr out of curiosity, when you reload do you press Ctrl + R or hit the reload button?

SNathJr commented 5 years ago

@kzidane I usually press the F5 key to reload the page.
