Server Error Each Time I open iCal on iMac, no trouble on iCloud
There is an event that opens up each time I open iCal on the iMac.I get a message, "The Server Responded with an Error" followed by the event. I copied the info from a Facebook post to create the event, but I can't seem to delete it or get rid of the event; iCal is frozen and I have to forcequit each time. There is no trouble on my iPhone, iPad, or iCloud. I don't know how to find this event file to delete or clear it out. I've searched under .ics files, but they are all from 2013, seems nothing from this year.
Any suggestions?
Thanks,
Jennie
