Thumbnails slider is too wide! Please reduce the number of thumnail images or size. in HOT Joomla Gallery

When HOT Joomla Gallery load in ie9, safati and chrome I found the error message like "Thumbnails slider is too wide! Please reduce the number of thumbnail images or size."

SOLUTION:
write below code in the header section and reload the gallery page.

<?php
//remove mootools.js and caption.js
$headerstuff=$this->getHeadData();
reset($headerstuff['scripts']);
foreach($headerstuff['scripts'] as $key=>$value){
 unset($headerstuff['scripts'][$key]);
}
$this->setHeadData($headerstuff);
?>

and find out the below syntax in header of index.php page and comment it.
JHTML::_('behavior.mootools');

I Hope it will help you:)
