Hi, after an upgrade of zope 2.2.0-1 the calendar doesn't work. (I have no valid backup of the old version :o( ) I have override (the directory) the old version of the calendar with the new version 0.9.17, but I get errors. In the new directory doesn't exist a calendar.pyc. Do I need this file and how can I create this??? I can't programming in python. How can I solve this problem???? Thanks Frank
