All web browsers have cache files saved on you computer, cache files make searching the web faster. When you go to any site on the Internet you browser will store all of the files on each page you visit. The browser is suppose to look to see if any of these files have been updated and if so replace them, unfortunately this doesn’t always happen and sometimes will generate errors. You can fix this by clearing your web browsers cache files (see instructions below) forcing your browser to download the new files.
