I'm using two plugins that seem to clash:
http://wordpress.org/extend/plugins/simply-poll/
http://wordpress.org/extend/plugins/the-events-calendar/
When both activated only the poll plugin shows in the admin menu but when it's deactivated the calendar plugin shows in it's place.
Is there a way to get both plugins working together as they're exactly what I need. I'm running the latest version of WP.
p.s It's more than likely that the problem lies with the poll plugin!
