Javascirpt not working in Event Espresso after updating to latestversion


We have Event Espresso installed in our site. After upgrading to the latest version it seems the javascript on the plugin is not working

Try to duplicate ticket and event time but nothing happens

also when i try to open the add featured image it should pop up a window where i can choose the image but it just oepnes to a new window. i think this is also connected withe the javascript not working right

I try adding media in pages and working fine. seems an error with the javascript the plugin is using

Any advice
