We have a very strange problem on our site where we are unable to add any events to one single date, namely 30th September 2012. Any other date no problem. The event can be entered without problem from the Admin side of WordPress and is there on the calendar but does not show up when viewing the site from the visitor perspective.
I'm guessing this is probably some sort of data corruption issue as I can't see anyone else having reported this.
This issue has been with us from the very first day of installation of the calendar plugin which we have run successfully for a good few months now.
Any suggestions as to how we can fix this would be gratefully received as we our calendar is already filling up for the whole of this year with the exception of this one day which we can't do anything with. We have a huge number of events on the calendar and are therefore worried about losing any of this data so hope there is a simple remedy.
