Cookies are text files that websites may use to store information on your computer. This helps the website to log you in, remember your preferences, etc. Most cookies (including all of the cookies that we use on our site) are completely harmless. However, it is a good idea to remove cookies from time to time, especially if you are experiencing errors on a website, such as log in problems.
Some browsers allow you to clear cookies from the last hour or last day. While this may solve your problem, in many cases it won't clear the older cookies which might be causing the error. We recommend choosing "everything" or "the beginning of time" if your browser gives you that option.
