For a client i bought The Eventscalendar Pro plugin, and installed it on a testdomain. Now i want to install it on its definit domain (nieuw.sijthoff-leiden.nl), but (logically) the license key hits it ceiling. How to solve this? I’ve uninstalled it on the testversion. Does the problem also occur when i put the website on its definitive location, sijthoff-leiden.nl?
