The version was 2.0.10. By “Now when you go to update and event you end up on a blank screen” I mean update an existing event or add a new event. All previous events still exist.
After deactivation and reactivation both Event Calendar and Event Calendar Pro, it now works! Sorry. Expert in Joomla and new to Word Press. Thank you!!
New issue is that a short list of Upcoming Events on the right hand side of the home page is coming up blank. http://hippocratesinst.org/ Any help would be very appreciated.
