Currently trying to use All-in-One Event Calendar.
Everything works great except events details page.
Apparently this is a common issue as the devs have explained about here:
Event details on the event detail view show up in the header, body, footer and any other separate element. (see pic)
It appears that there is a conflict with the theme and how it shows custom content types.
I have the easy custom content types plug in, so it shouldn't be a problem to sort.
However, due to my noob skill level and lack of time, it would be great to get this sorted before the site goes live in a few days.
