Clear Your Browser Cache

All major web browsers cache website components such as HTML pages, images and stylesheets. The first time you visit a site, the browser will save pieces of the site, because the browser can display the files stored in its cache much faster than it can pull fresh files from a server. The next time you visit that site, the cached files will help cut down the page load time.

This improves performance, but it can create errors or inconsistencies if the cached information falls out of sync as the website evolves over time. This is when you may encounter browser errors like run time error, buttons missing on the page, the action you are trying to perform not completing, etc. Clearing browser data (also known as clearing your browser cache) may fix these kinds of errors. Instructions on how to clear all or selected portions of your browser's cache are provided below.

Please be aware that clearing browser cache can remove some information you may want to keep, such as browsing history and cookies (saved data like your email address or name.)  Please bookmark your preferred sites and ensure you know all your passwords before clearing your browser cache.

Please note that the specific steps for each browser may change as the browser updates to a new version. If you are having trouble following these steps, try searching these terms in your preferred search engine: "clear cache" and the name of your browser (Chrome, Internet Explorer, Safari, Mozilla Firefox, etc).
