I've got a problem with the display of two festivals, both lasting several days. The first (Haddington Festival) should show from 21st May to 31st May but misses out Friday, Saturday and Sunday.
The second (3 Harbours Festival) runs from Sat 2nd June to Sun 10th June but on Sunday 3rd the box sits on top of the all day event marker.
I'm using the Suffusion Theme.
Otherwise, love the plugin!!
