Something doesn't look right. What should I do?

If a site looks strange or if something on it isn't working properly, you can often resolve the issue by clearing your browser's cache and deleting your cookies. Try clearing the cache first, then if that doesn't work, the cookies.

Don't be intimidated by the info below; both techniques are pretty easy. Just click your browser below to see customized instructions.

What are 'cache' and 'cookies' anyway?

A browser's cache is just some of its memory that's devoted to remembering what a page used to look like. Using cache, browsers can open pages they've seen before more quickly. If anything goes wrong in the cache, or if the page has changed since your browser last saw it, it can affect how the page displays.

Cookies are tiny files stored by your browser that remember your personal settings. When you go to a site you've been to before, the cookies remind the site how you like the info on it to be displayed. They remember, for instance, your SafeSearch settings, and what view you like in Google Maps. Sometimes they break and make pages look weird.
