What operating system do you have? What browser? What is the error message? What were you trying to do when you got the error?

Clear your Browser cache and history, also you should consider trying a different browser if the error persist. Not knowing what browser or OS you are running I will also add the standard - Run all OS and application updates and verify that your AV software is updated and operational.

Google chrome, mozilla and internet explorer. It always says that, "Sorry, something went wrong."
