I have installed the plugin on a WordPress site on http://www.slankenlijn.nl/berichten/afvallen/wil-jij-afvallen-probeer-het-weekdagdieet-2/
All share buttons are working correctly, except for the email button. When I click on it, it doesn't open the email window.
Do I have to put in my e-mail address somewhere? Or do I have to change some other setting in WordPress?
Would love to hear from you.
