I really have no reason to stick around on this site if these issues persist
I have no way to test my games or even view them outside of studio
I have no way to player other people’s creations
I can’t even scroll through my own profile or view my own inventory
Sounds like you have something on your computer which is blocking js.rbxcdn.com, which is the site from which ROBLOX’s JavaScript is served. Try disabling your browser extensions one by one until you figure out which one it is. If that doesn’t work, it may be a firewall or antivirus.
