In_array warning on Calendar

Hello,

We’ve been getting the same error on our calendar page:

“Warning: in_array() expects parameter 2 to be array, string given in /home4/still1885/public_html/wp-content/plugins/my-calendar/my-calendar-event-manager.php on line 3462”

I’ve deactivated and reactivated the plugin, and the latest version is installed. I’m unsure how to see if other plugins are interfering if they are. Any help would be appreciated.

Thanks!
Jay
