Errors occur for many reasons. They can happen due to changes with versions of software, user input errors, security issues, internet problems, etc. An error message is a negative event, but you should take the issue and use the error to help you improve or understand your application or website. Quite often, these problems may not have been initially recognized. Solutions for these problems give you a better application or website.

Common issues include [website errors](https://www.inmotionhosting.com/support/website/error-numbers/http-error-codes/), email errors, and application errors. Recognizing and reporting these messages will help your support personnel or developers resolve issues quickly.
