Cannot create static pages after plugin deletion

Hi,

I am running into a problem where I can no longer add pages to my site under my events section. I’m sure it had something to do with me disabling and deleting the Events plugin.

This static page works fine: http://nycaamh.jimmyzhou.com/events/
but when I tried to create sub pages, it just shows the homepage content. http://nycaamh.jimmyzhou.com/events/2012-past-events/

If I create a page in a different section, it works: http://nycaamh.jimmyzhou.com/get-involved/test-page-3/

Any ideas? Any help will be appreciated.

Thanks,

Jimmy
