Plugin doesn't work in the site

Hi there,

I have a few questions, and thought it would be best to ask them all here:

1. I can't seem to get the plugin to work properly @ shaneymarie.com/appointments

2. How can I have only specific times and specific days available in the [app_monthly_schedule] (i.e instead of "working hours")

Thanks a lot for your help!

Kind regards,
Fernando.
