This quick tutorial will show you how to clear your browser's cookies and cache. Browser cache is generally used to load stored images quicker the next time you visit the same site.
Browser cookies, on the other hand, are text strings that hold user preference information, such as when you log in to your web e-mail account or add items to your shopping cart. Some cookies can be somewhat of a privacy concern for users, therefore, it's a good idea to clear them every so often. However, if you set your browser to reject all cookies, it will cause some websites not to function properly.
Clearing your browser cookies and cache is also an important step if you've fixed a hacked WordPress site. Without clearing them, you're site may still not look right.
