Sometimes, your web browser will retain old data (otherwise known as cookies or a cache) which needs to be cleared from time to time. If you encounter a forbidden or unauthorised error message, this should be the first troubleshooting step to try.

Clearing the cache varies depending on which browser you choose to use. Log out of your Op Central account first before performing any of these options, and keep in mind that if you are clearing your entire cache (or browser history) then you may be completely signed out of any other websites you are logged in to. We recommend only clearing the cache on Op Central if you are able to.
