Studio won't open any places

This is a problem one of my friends is getting. Here’s the output he receives:

Apparently all he gets is skies coupled with that error. Is there a fix for this?

I get it as well, my guess is it has something to do with a security cookie on your computer getting changed, and it no longer matches the one on the server, a fix is to close roblox and re-open it

Thank you for the suggestion. I told him to do what you suggested and it appears to have been fruitless for him. If it is of any help the error first shows up in the roblox studio browser not in the game itself.

Tell him to log out/log back in, and if that doesn’t work, reinstall ROBLOX.

^^^^^^

All those errors he’s getting are forbiddens and login errors. Sounds like he needs to clear his cookies, login, or something to the effect of making sure he is signed out.

Tell him to follow these steps and reopen studio.

It should fix it, I have had the same problem before.

Only problem: I’m a Firefox user, which means it’s not just IE’s fault, also, why would this matter to studio what your internet browser does?

I believe that the QtWebBrowser uses IE’s settings (Control Panel -> Internet Options) if available. That’s why you have to do that.
