We are using a custom WordPress theme created by an outside vendor. This morning we tried to perform the update to WordPress 4.1, after it was updated we started testing the site. When I went to the events page all of the events were missing. I went into the plugin through the dashboard and all of the events were completely removed from the site. We had a back up, so we were able to get everything back up and running, but I need to be able to update WordPress.
Have you heard of any others with this issue? Do you have any suggestions for us?
