I bought a single site license and I received the downloaded zip file on my computer, but I don't know what to do with it?
At the moment I have this error message in Wordpress:
Gravity Forms is required.
You do not have the Gravity Forms plugin enabled. Get Gravity Forms.
In WP, go to Plug-Ins, New and download. Find the file on your computer and upload to your site.
Installing Gravity Forms is a little different than installing a plugin from the WordPress plugin repository. Since you have the plugin zip file on your computer, you can go to this URL for your website:
http://example.com/wp-admin/plugin-install.php?tab=upload
Just replace "example.com" with the domain for your website. That will take you right to the Plugins > Add New > Upload tab. Now, click the [Choose File] button to open the file dialog, then find the zip file on your hard drive, click it, and then click [Install Now] button.
Once that is complete, you just activate it like any other WordPress plugin, and you can insert your license key to enable automatic upgrade notifications.
