How to Manually Update PBS with a Plugin Zip File
Note: Do this when you already have PBS installed and activated, and you want to update it with a zip file that you downloaded from the site, or from an attachment we sent you from an email.
Note: We're using another plugin to perform updates, this allows us to update PBS right away without the need to uninstall it first.
Go to Plugins > Add New, then in the search box, search for the plugin "Easy Theme and Plugin Upgrades"
Once you find the plugin, install and activate it.
After activating the Easy Theme and Plugin Upgrades plugin, go again to Plugins > Add New, then click on the Upload Plugin button near the top:
Choose and install the Page Builder Sandwich zip file,
That's it. Now you should have the new version of PBS.
