For optimized loading, Web Browsers keep a cache of files and images for recently visited websites. This avoids having to download the pages each time you visit a page. This optimization can sometimes cause problems when the browser reads from its cache instead of downloading the latest page. This can cause unexpected behavior such as the following: - The page looks partially loaded. - The page looks like it has loaded but the page has strange or unusual formatting. - Images on the page are in the wrong places. - Strange login and license activation issues. ## Clear the Browser Cache You can easily fix cache issues by clearing the cache.

This forces a refresh with an empty cache on all browsers. - Press the **CTRL + SHIFT + R** key combination to force an empty cache refresh. For **Safari**, press **CMD + R**. - Hold the** CTRL + SHIFT + DELETE** key combination to open the clear browser history menu. For **Safari**, press **CMD + SHIFT + DELETE**. Make sure to choose the cache option and the largest time range possible to clear the entire cache. ## View and Clear Browser History Often, clearing the Browser History can help fix issues.
