To clarify, are you unable to see the new “Events” section within your admin (https://cloudup.com/chuYr09esgJ). If not, can you verify that you have both our free version of the The Events Calendar and the Pro version installed and activated on your site?
Both Plugins are installed on and I see the events menu panel but when I click on setting I see all the horizontal tabs but I don’t see any data under each tabs.
Would you mind turning on WP_DEBUG and seeing if there are any particular errors that are showing up on that page and preventing everything from loading?
