EasyLayouts can be kept up to date using the Joomla updater - to do this you need to enter your download id in the EasyLayouts config.
Your your EasyLayouts subscription page (at https://www.easylayouts.net/members/subscriptions) you can get your download id and also see a list of sites you are currently receiving updates for. Note that the list of domains is empty until you fetch your first updates then it is automatically filled.
Simply enter this in your EasyLayouts config (on the first tab) along with your EasyLayouts username:
After saving your config the Joomla updater on your site will pick up EasyLayouts updates. It should also work with PerfectDashboard.
