I couldn't reproduce his problem.
On his site the plugin produces this code:
<script type="text/javascript">
var cforms = jQuery.noConflict();
Date.dayNames = ["S","M","T","W","T","F","S"];
Date.abbrDayNames = ["S","M","T","W","T","F","S"];
Date.monthNames = ["January","February","March","April","May","June","July","August","September","October","November","December"];
Date.abbrMonthNames = ["January","February","March","April","May","June","July","August","September","October","November","December"];
Date.firstDayOfWeek = 0;
Date.fullYearStart = "20";
cforms.dpText = { TEXT_PREV_YEAR:"Previous Year",TEXT_PREV_MONTH:"Previous Month",TEXT_NEXT_YEAR:"Next Year",TEXT_NEXT_MONTH:"Next Month",TEXT_CLOSE:"Close",TEXT_CHOOSE_DATE:"Choose Date",ROOT:"http://www.choreboyz.net/wp-content/plugins/cforms"};
cforms(function() { Date.format = "dd/mm/yyyy"; cforms(".cf_date").datePicker( {startDate:"01/01/1899",verticalOffset:10,horizontalOffset:5,horizontalPosition:1 } ); Date.format = "mm/dd/yyyy"; });
</script>
which I can't reproduced - I imported/exported his settings to my test setup but this code doesn't appear. I think this codecauses the problem because the theme runs the noconflict() mode and the line
var cforms = jQuery.noConflict();
suggests that the plugin also tries to activate this mode.
Please try to create new forms or download sample forms via admin menu.
