OK the Check out button is there now.

Now I get a “Error checking out! Result code is 0.”

Hmmmm

OK looks like I found a solution though it may be a bit clunky.
in the plugin itself I added the following code:

$this_page_up = $_SERVER[‘REQUEST_URI’];
if (strpos($this_page_up,”wp-admin”)) {

…. plugin code…

}

Basically if the wp-admin directory is not in the URI then the plugin is not run.

What is a better way?
