[Plugin: All-in-One Event Calendar] All events displaying in one day

Hi – just installed this plugin today.

Have been adding dates for the coming months, and when I got to June, it seems all events I have added so far, are also being displayed in one particular day (9th June if it’s significant).

I have checked each event, there is no mention of this date in any of them. They are displayed as expected for their “real” dates.

Looked through the forums and couldn’t see a similar issue reported.
