Hey there fhunkziker. Thanks for reaching out here, and apologies for the inconvenience you're faced with so far. What version did you update from and to? Was it going pre-2.0 to 2.0.8, or a less significant jump?
I'm not sure where that message you're seeing is being generated, because I haven't ever seen it in our code and cannot locate it now either. Also confusing is the fact that you're noting events showing on the homepage...which they wouldn't do by default unless you'd either had a widget in place previously that was removed, or template modifications were made in the core plugin itself that got lost on the update. Any chance either of those could be responsible here?
Let me know if so - a link to your site would be awesome, if you have it - and we'll try to troubleshoot from there. Thanks in advance.
