# Cache does not purge automatically

 * On 4th May I installed Simple Cache on a site and set the “Expire the cache after”
   value to 60 minutes. Compression scrambled the signal comprehensively so I left
   that off.
 * In the meantime I updated to version SC 1.4
 * This morning I was alerted to the fact that visitors who are not logged in were
   seeing a version of the page from 5th May.
 * If it tells you anything, the tag at the bottom was:
    <!– Cache served by Simple
   Cache 1462491359 –>
 * As this site has had a couple of different home pages since then this is not 
   a good thing.
 * I pressed the “Clear Cache” button, and the cache has now updated, but my expectation
   was that it would happen automatically every hour.
 * Is there something I might be missing?

 * Thanks Taylor, I’ve just updated so hopefully the client will be happy again.
 * It has occurred to me that I may have misunderstood what the setting “Expire 
   the cache after” does. Is this documented anywhere?
