since adding k2 to my website, www.outbackgolfbar.com ,new registrations when trying to create a new account are presented with a blank page. If I switch off the k2 system plugin, it works OK. When I check the same setup on my wampserver, I get the following error message - Fatal error: Call to a member function def() on a non-object in C:\wamp\www\components\com_k2\templates\register.php on line 31.I cannot find any advice on how to solve the problem. Anybody?
