An error is a piece of information displayed when an unexpected event occurs. Error messages are used when user intervention is required, to indicate that a desired operation has failed, or to relay important warnings—such as warning a computer user that they are almost out of disk space. Error messages are seen widely throughout Roblox and are part of every Roblox version.
On the game client, if an error has occurred, a said error will appear in the center of the screen in the form of a gray dialog box, which will tell the user specifics about the error and give them multiple methods to proceed. On the website, the error will appear in the form of a separate page, typically with a Roblox-themed image to go along with it.
|ID # (Error Code)||Description||Images|
|Down For Maintenance||"We're making things more awesome. Be back soon."
Displayed when the administrators have locked down the site in order to fix something that went wrong in the background. This screen is also used for when the site is closed for maintenance. This is what the test websites currently lead to. The buttons spelling out ROBLOX and the text box are used when the administrators need to enter a password to start making changes to the website.

The page isn’t redirecting properly (Firefox)
This page isn't working; www.roblox.com redirected you too many times (Chrome)
Displayed on accounts with a NotApproved.aspx-type ban or a poison ban. This error occurs because the site tries to redirect to the Membership/CreationDisabled.aspx page, but when banned, all pages redirect back to Membership/NotApproved.aspx, creating an infinite redirect loop.
