Okay, es lag an einem neuen Plugin, das ich erstellt hatte für den Hook "global_start", um die anstehenden Termine in einer Sidebar anzuzeigen. Offenbar affektierte das auch die Termin-Erstellung (warum auch immer). Gelöst habe ich es, indem ich einfach die Ausführung des Scripts im Kalender mit
if (... && THIS_SCRIPT != 'calendar')
deaktiviert habe, und jetzt geht es.
Hier das komplette Plugin-Script für den Hook "global_start":
if ($vbulletin->options['showevents'] && THIS_SCRIPT != 'calendar')
