How to Clear the Cache in Joomla
When caching is enabled Joomla will make a temporary directory to store files that have been visited during a certain period of time. This can prevent seeing immediate changes in the front end.

1. Go to Site > Maintenance > Clear Cache.
2. Place a check mark at the top of the column to select everything.
3. Then click on Delete in the toolbar.
   

Your browser also has a cache that may need to be cleared.
