I downloaded the latest b2evolution version 2.1-beta, codenamed "Las Vegas" the installation and other configuration went well until I got to the users section where I received this error. I have used b2evolution in the past without any problem this could be part of updates.

This is the error: Undefined variable: template in D:\www\htdocs\xxxxxxxxxxxx\aiscarticles\inc\_core\ui\forms\_form.class.php on line 198
