When you visit a website, in order to make it work, your web browser downloads various files from a server, containing HTML, JavaScript, CSS, images, etc. Some of these files are normally saved locally, on your computer's hard drive, in a form of temporary storage called the browser cache. The next time you visit the same site, your browser can speed things up by loading files quickly from its local cache rather than waiting for them to download over the internet again. However, when a web application, like the Learninglogics® LCMS, is updated, that can mean that you're not running the current version, but rather an older version that's been stored in the cache.

Sometimes it will therefore be necessary to delete your cache in order to make sure you're accessing the latest version of the LCMS. The instructions for doing this are virtually identical on all major web browsers. You can reach the relevant settings through your browser's menu system. However, the easiest way to do so is by simultaneously pressing a hotkey combination consisting of the control, shift, and delete buttons (CTRL+SHIFT+DEL). This is a standard shortcut across all browsers. Note: Be careful not to press CTRL+ALT+DEL, which interrupts the current program to invoke Windows Security, a dialogue screen allowing you to log out, shutdown, switch users, etc.
