No Search or Past Events showing on Events page.
Ning To Jamroom
I think 'event_url' should be 'event_title_url' and that is a url version of the event_title tagged onto the end of the event page url to make it 'search engine friendly' and is generated by Jamroom.
'event_website' is a field imported from Ning. To get access to it on the event create/update forms use the form designer from those forms and create an 'event_website' text field with its validation set to URL.
To then show that on the events page, open the event module's template editor and edit the item_detail.tpl file. Enter something like this where you want it to show -
Website: <a href="{$item.event_website}">{$item.event_website}</a><br>
