What does a 400 message mean on a website?
Answer
The http 400 family of codes are issues that originate on the client’s end of a connection. That means your server isn’t at fault when you run into any of these codes. The most likely solution is to clear your browser cache and cookies.
For more information about different types of 400 messages, please see this website.
If clearing your cache does not solve the problem, please contact the Office of Information Technology for help.
