** UPDATE: This issue has been resolved **
The plugin update 2.1.5 for the All-in-one event calendar by Timely has conflicted with our system. Clicking into an event takes the visitor to a missing link page. We are currently working with their support team to get this issue resolved and to bring back the event detail pages. Because this plugin updates the database we are not able to roll it back at this time. We’ll keep you posted on updates and also let you know when the issue is resolved. Please email lsa.web.support@umich.edu with any questions.
Best,
Web Services & LSA-IT
