After upgrading to 1.6 (2006050506) on Friday, the enrolment plugins page is not working. It will display only the top section:
|Please choose the enrolment plugins you wish to use. Don't forget to configure the settings properly.
You have to indicate which plugins are enabled, and one plugin can be set as the default plugin for interactive enrolment. To disable interactive enrolment, set "enrollable" to "No" in required courses.
Rest of the page is missing. Running on IIS6, PHP 5.1.1, mysql 5.0.18.
