Using Joomla

Purge Expired Cache

When the cache refreshes, the old cache files are not removed. To purge expired cache, simply click Tools→Purge Expired Cache. You should see a screen such as the one in Figure 16-4.

Warning

Pay close attention to the warning listed in Figure 16-4. If you have a large number of expired cache items, consider performing this action during a time of day with lower traffic.

Once you have read the warning message and are ready to proceed, click the “Purge expired” button in the top toolbar.

Figure 16-5 shows the Cache Manager screen after the expired cache has been purged. Depending on site traffic, you should notice most or all the cache files are now purged.
