There has been an error processing your request. Events+

Hi, In events+ I'm getting another error " There has been an error processing your request. Please, reload the page and try again." I am also getting a second set of "I'm Attending" "Maybe" & "No" buttons set way off the page in the bottom corner of the window (see pic) The only change I made was to activate WP smush pro again... I tried to deactivated it again but the error still loads. Access is given. Any help is appreciated.
Thanks Suz
