Running my calendar 1.8.9 under 3.2.1 for about 5-6 months without issue. The only problem that recently occurred is that the weekly event calendar on pages shows a week in advance.
Server time is accurate, calendar/posts etc show the correct date, just the weekly calendar is reporting wrong. This effected multiple weekly calendars pulling different event series. Adding new shortcode generates the same issue.
Could it be corruption in the database or maybe something with the new year?
To my knowledge, nothing changed on the server, wp, plugins or settings. Could not find a post with similar problems...
