The Commercial tab is missing from the Plugins page when trying to update Types 1.7
I have Types installed and registered on my live server, but also want to get it installed on my development server (which of course has a different URL so will have to be registered separately).
However, the Commercial tab is entirely missing from my Plugins page on the development server - I also can't get to it manually by going to http://localhost/wordpress/wp-admin/plugin-install.php?tab=commercial, which should otherwise work. Below are screenshots from my development and live servers respectively.
Without this, I can't register Types, and therefore can't upgrade it automatically, which I want to do on the development server before I'm happy upgrading on the live server.
Both servers are running the same theme. The development server is running on WAMP, whereas the live server is LAMP, but I don't see that that would make a difference.
Is there some setting I'm missing to get the Commercial tab to appear?
