So, instead of: console.log(‘foo’); Use: window.console && console.log(‘foo’); …and you won’t get any errors.

Updatier: The Mene+Shuman fix now is busted with Firefox 30 and Firebug 2. Firefox 31 may provide workarounds (will investigate).

If you want Upcoming Events, you want just the first <div class=”events-horizontal”>, then just grab the <div class=”title”><a href=”…”></div> tags, so the links on titles: upcoming_events_div = soup.select_one(‘div.events-horizontal’) … Read more
