When I first did the upgrade I re-saved the permalinks in both the WordPress settings as well as the Events Manager Settings. That did not help me either. I am beginning to think it is my theme that is causing the issue but I cannot pinpoint it. I tested this in my development environment with a different theme and it seemed to work. however, using it with the theme I have now, it does not seem to like the custom post types.
I am using the Startup theme from HighThemes. I have a static homepage set with a static Blog page as well. I am not sure if that is causing the issue.
Also, within the EM plugin settings I have changed the Events List/Archive to read from a custom page I set up, Classes. The events show up fine when you view that page. However, when you select a particular event it sends you to the page where it should be but with whatever content is in the no events field in your settings.
Any suggestions on what might be causing that to happen?
