When I activate the Event Calendar 3.0 plugin, I get "Done, but with errors on page" in the status bar when I load the blog page - even if I don't have the tag inserted anywhere to call the calendar. I don't otherwise have any problems but, naturally I don't want yellow warning signs flashing on my site. Any one have any idea what the problem could be? A clash with code from another plugin? I don't think it's the template because I switched back to the default and still got the error.
PS: I'm a total newbie
