From your account page in this site or from the addons panel inside the plugin (but you need to install previously the addons manager to install directly from the blog).
I am just trying out this neat plugin and this is what I see after trying to click in the account link:
Fatal error: Call to undefined function tnp_buy_button() in /home/thenewsl/public_html/wp-content/pages/account.php on line 112
The site is experiencing technical difficulties.
I am trying to understand the free ones, but not working in the panel and have the account error. It says free in green, but no click install. Isn’t it working?
Maybe this makes it easier when you have an account. I think probably the Archive, Locked Content, WP Users, and Extension Manager are pretty interesting. I don’t have Buddy Press or Translatepress. Now to explore them!
