Allan, 
 It means that user w**** (whoever that is) has something in their Safari cache. 
 Log into their account. Click on Safari. At the top left of the screen, click on Safari > Clear History... In the pop-up screen, change Clear to "all history", and then, click Clear History. Again at the top left of the screen, Click on Safari > Quit Safari. This should clear their entire Safari cache. 
 *They will need to log back into all websites and services they were logged into before.*
