I'm using the widget from "amr ical events" plugin. After updating my plugins, the widget now outputs the following error:
Ungültige Ical URL http://www.ec-nordheide.de/?ical
Note: the php validation functon does not cope with internationalised domain, please contact the developer if this affects you.
I tried a bit with the URL, if I delete the hyphen, the error disappears (but the file can't be found anymore) ... what do I do?
