I can not belive what the problem is...
Who ever coded the YT Framework made VERY BIG MISTAKE, and should be corrected ASAP....
Why in the world would you replace the entire head script/javascript declaration with an empty string ????????
@Bandola the problem resides in file
/plugins/system/yt/yt.php at line 76 which goes like this...
$doc->_script['text/javascript'] = str_replace($doc->_script['text/javascript'],'',$doc->_script['text/javascript']);
Just comment this line, prefix it with "//" so it goes like
// $doc->_script['text/javascript'] = str_replace($doc->_script['text/javascript'],'',$doc->_script['text/javascript']);
and your problems are gone....
I really can't belive this... In over 10 years of Joomla development i haven't seen something like this.... Good Joob YT Team....
