Problem mit Installation des "The Events Calendar Widget"

Wenn ich The Events Calendar Widget" installiere, erhalte ich die Meldung

Warning: include_once(/home/vhosts/5000136526/taktberlin.org/htdocs//wp-content/plugins/the-events-calendar/lib/widget-list.class.php) [function.include-once]: failed to open stream: No such file or directory in /home/vhosts/5000136526/taktberlin.org/htdocs/wp-content/plugins/the-events-calendar-widget/the-events-list-category-widget.php on line 15

Ich habe dann keinen Zugriff auf den Plugin-Ordner und muss das Plugin via Filezilla wieder entfernen.

Hat jemand eine Idee`?
