Plugin version 1.8.2
On the Titles & Metas page of the SEO plugin there is no content displayed when All-in-one Event Calendar is also active. I get this scripting error:
TypeError: allday.get(0) is undefined in jquery.timespan.js line 305
allday.data( 'timespan.initial_value', allday.get(0).checked );
Plugin authors in general should load their scripts only on the admin pages that needs it.
