To clear the page cache in MediaWiki, you have to add the below line toward the finish of the URL of that page in the location bar of your program.
– '&action=purge'
For example:
http://www.mydomainname.com/index.php?title=Main_Page&action=purge
In the event that you have not signed in, an alert message will be shown inquiring as to whether you might want to clear the cache from the page.
