Error

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 hard disk space). Error messages are seen widely throughout Roblox, and are part of every Roblox version.

When on the website, most error messages will be the only content shown on-screen besides the header and footer.

On previous Roblox game client versions, error messages used to be often displayed using a red rectangle at the top. However, the newest versions now use a gray dialog box in the center of the screen.

Common errors are:
 * Unknown error
 * 403 error
 * 404 error
 * 500 error
 * Old Roblox error page
 * 400 error
 * Bad Request
