CUNY Academic Commons

Upon activating the Events Manager Plugin (feature #2007 http://redmine.gc.cuny.edu/issues/2007), the site on which it is activated (globalization.commons.gc.cuny.edu) is no longer accessible and all pages within the subdomain produce a HTTP 500 server error.

Steps to reproduce:
1. Activate Events Manager Plugin
2. "Activation" page does not load
3. Manual navigation to other pages within both wp-admin as well as the base domain are unsuccessful and result in a 500 server error.

Notes:
-I can't access the wp-admin pages to disable the plugin
-it appears that pages are attempting to automatically reload themselves but eventually time out on the server with a HTTP 500 error
-there is the possibility that the plugin is conflicting with existing database "junk" that is a remnant of previous plugins or an artifact from the initial database import from a single WP installation.
-I will attempt to install the plugin on a fresh site to see if it is site-specific.
