I got some problems with the latest versions of League Manager. When i shall press the "League Manager" icon to insert shortcode or whatever it says "The website cannot display the page". I have attached a image of it. The version that i've tried with and got the same errors with are 3.6.8, 3.6.9, 3.7, 3.8. And my WordPress is 3.4.1. Any ideas what this could be and how to fix this issue?
