Jquery conflicts happens for the below reasons...
1. Calling same script more than one time in page
2. Assigning non-existing path
3. Improper reference to the contols
Solution-
1. Use
jQuery.noConflict();
2. Order your script in proper manner
I) jquery(latest or higher versions)
II) jquery-ui
III) newsticker etc...
3. Avoid calling same script more than one time
4. Only one script can do many functionality. So verify yourself and avoid using more scripts.
Ex:
<script src="Script/jquery.calendars.validation.js" type="text/javascript"></script>
is enough for calander. So u can remove
<script src="Script/jquery.calendars.validation.min.js" type="text/javascript"></script>
Hope these suggestions helps you...
