Instructions how to clear the cache with various Internet browsers:

The cache is a buffer memory, which helps to avoid long loading periods of a website. Data that has already been loaded remains in the cache so that it can be retrieved faster on a later occasion. For display errors, it is therefore helpful to first delete this cache.

To clear the cache, proceed as follows:

Internet Explorer

  • The procedure for clearing the Web cache in Internet Explorer (IE) depends on which version of IE and Windows you are using. The options for removing cached web pages can be found in IE under "Tools" ("Internet Options" or "Security") and then under "Browsing history".


  • Click the menu button and choose Options.
  • Select the Advanced panel.
  • Click on the Network tab.
  • In the Cached Web Content section, click Clear Now.


  • On your computer, open Chrome.
  • On your browser toolbar, click More → Tools → Clear Browsing Data.
  • In the "Clear browsing data" box, click the checkboxes for Cached images and files.
  • Use the menu at the top to select the amount of data that you want to delete. Choose "beginning of time" to delete everything. 
  • Click "Clear browsing data."


  • On a Mac PC, use the keyboard shortcut "cmd" + "alt" + "E".
  • On a Windows PC, empty the cache using the shortcut "Ctrl" + "Alt" + "E". 


By default, Opera clears the cache when you exit the browser. If you have disabled this option, you can clear the cache manually:

  • Click on the "Opera" button in the upper right corner and select the "Settings".
  • Go to the Advanced category above and select "History" on the left side of the menu bar.
  • Click "clear now" to delete the current browser cache.
