I’m getting the following exception as soon as I activate Tracking using 0.10.0.3 in a Network (both in the backend – in the WP-Piwik settings upon apply – and in the frontend – in the footer where the tracking code would usually appear):
Warning: html_entity_decode() expects parameter 1 to be string, array given in [...]/wp-content/plugins/wp-piwik/classes/WP_Piwik.php on line 1065
PS: I also lost all settings and the WP-Piwik network overview reports all pages as not yet created. So it seems like WP-Piwik is unable to determine the page ids.
