Ok, I guess it is Joomla 2.5. Try this, instead of deleting the jQuery part of the template, change it with this:
Code:
<?php if (@$_REQUEST['option'] != 'com_jomres') { ?>
<script type="text/javascript" src="<?php echo $template_path ?>/js/jquery.min.js"></script>
<script type="text/javascript" src="<?php echo $template_path ?>/js/jquery-ui-1.8.13.custom.min.js"></script>
<script type="text/javascript">
jQuery.noConflict();
</script>
<?php } ?>
