I've this error in my own J template, where jquery is linked by script tag.
Error occurres in this script:
$(document).ready(function(){
$('.login-dropdown').click(function() { //this passes (tested with alert)
$('.login-container').show(); // there is error
});
});
for record - .login-container has display:none which could by right for show() method.
I suspect the conflict between jquery and joomla, but do not know how to deal with it eventually.
Thank for any help.
