This article explains how to use the Wordify DashBoard to clear the Smart Cache.
How do I clear the cache?
If you have updated static objects that have been changed on your site and need them to be immediately cleared from the Smart cache follow these steps :
From the Sites Page, Click the Pencil Icon next to the site you wish to update.
On the Details click the Clear Cache button in the top right hand corner.
This will reset the Smart Cache deleting all static objects inside it. If you CDN is enabled this will also clear your CDN so any updated static objects will be retrieved from the server and recached on the next visit.
