phpWebSite Calendar Date Quick Fix

Are you running a phpWebsite? Got a calendar that’s only showing the last two digits of the current year?

Open /mod/calendar/templates/view/month/mini.tpl and find:
{FULL_MONTH_NAME}, {PARTIAL_YEAR}

Change this to:
{FULL_MONTH_NAME}, {FULL_YEAR}

Reupload the template file and your problem is solved.
