Purge all cache
Site Administration > Development > Purge all caches
This setting is necessary when making changes to your theme or Moodle code in general. It removes the cached data, and so after refreshing your browser window with Ctrl + F5 you will see the changes you have made.
Moodle can cache themes, javascript, language strings, filtered text, rss feeds and many other pieces of calculated data. Purging these caches will delete that data from the server and force browsers to refetch data, so that you can be sure you are seeing the most up-to-date values produced by the current code. There is no danger in purging caches, but your site may appear slower for a while until the server and clients calculate new information and cache it.
To get to the purge cache option go to the Administration block then Site Administration > Development > Purge all Caches.
On this page you will get the text explaining its purpose and benefits followed by the Purge all caches button.
The process takes a few minutes.
