hi
the fix is this ::
Open file plugins/system/yt/yt.php, then you comment this code:
if($app->isSite() && !$k2detail && !$config_module && $layout== null && !$comMedia && $disMootool) {
// Remove default mootools
unset($doc->_scripts[JURI::root(true) . '/media/system/js/core.js']);
unset($doc->_scripts[JURI::root(true) . '/media/system/js/modal.js']);
unset($doc->_scripts[JURI::root(true).'/media/system/js/caption.js']);
unset($doc->_scripts[JURI::root(true) . '/media/system/js/mootools.js']);
unset($doc->_scripts[JURI::root(true).'/media/system/js/mootools-core.js']);
unset($doc->_scripts[JURI::root(true).'/media/system/js/mootools-more.js']);
unset($doc->_styleSheets[JUri::root(true) . '/media/system/css/modal.css']);
if (isset($doc->_script) && isset($doc->_script['text/javascript']))
{
$doc->_script['text/javascript'] = preg_replace('%window\.addEvent\(\'load\',\s*function\(\)\s*{\s*new\s*JCaption\(\'img.caption\'\);\s*}\);\s*%', '', $doc->_script['text/javascript']);
$doc->_script['text/javascript'] = preg_replace('%jQuery\(window\)\.on\(\'load\'\,\s*function\(\)\s*\{\s*new\s*JCaption\(\'img\.caption\'\);\s*\}\);%', '', $doc->_script['text/javascript']);
$doc->_script['text/javascript'] = preg_replace('%window\.addEvent\(\'load\',function\(\)\{\s*\}\);%', '', $doc->_script['text/javascript']);
//remove SqueezeBox.initialize in behavior.php
$doc->_script['text/javascript'] = preg_replace('%SqueezeBox\.initialize\(\{\}\);\s*SqueezeBox\.assign\(\$\(\'a.modal\'\)\.get\(\)\, {\s*parse\:\s\'rel\'\s*\}\);%', '', $doc->_script['text/javascript']);
// Remove call to JTooltips
$doc->_script['text/javascript'] = preg_replace('%window\.addEvent\(\'domready\',\s*function\(\)\s*{\s*\$\$\(\'.hasTip\'\).each\(function\(el\)\s*{\s*var\s*title\s*=\s*el.get\(\'title\'\);\s*if\s*\(title\)\s*{\s*var\s*parts\s*=\s*title.split\(\'::\',\s*2\);\s*el.store\(\'tip:title\',\s*parts\[0\]\);\s*el.store\(\'tip:text\',\s*parts\[1\]\);\s*}\s*}\);\s*var\s*JTooltips\s*=\s*new\s*Tips\(\$\$\(\'.hasTip\'\),\s*{\s*\"maxTitleChars\":\s*[\d]*,\s*\"fixed\":\s*false}\);\s*}\);%', '', $doc->_script['text/javascript']);
$doc->_script['text/javascript'] = preg_replace('%jQuery\s*function\(\)\s*{\s*\$\$\(\'.hasTip\'\).each\(function\(el\)\s*{\s*var\s*title\s*=\s*el.get\(\'title\'\);\s*if\s*\(title\)\s*{\s*var\s*parts\s*=\s*title.split\(\'::\',\s*2\);\s*el.store\(\'tip:title\',\s*parts\[0\]\);\s*el.store\(\'tip:text\',\s*parts\[1\]\);\s*}\s*}\);\s*var\s*JTooltips\s*=\s*new\s*Tips\(\$\$\(\'.hasTip\'\),\s*{\s*\'maxTitleChars\':\s*[\d]*,\s*\'fixed\':\s*false}\);\s*}\);%', '', $doc->_script['text/javascript']);
$doc->_script['text/javascript'] = str_replace($doc->_script['text/javascript'],'',$doc->_script['text/javascript']);
if (empty($doc->_script['text/javascript']))
unset($doc->_script['text/javascript']);
}
}
