Like the title, my quick reply ajax is not working anymore. It's always loading!
I thinks it's not about jQuery and Prototype conflict, because I'm using jQuery.noConflict() and jQuery instead $ everywhere.
You can try to revert postbit_classic template to default, after that implement your customisation.
BUT, you have to make sure that you have this code in your template:
<a name="pid{$post['pid']}" id="pid{$post['pid']}"></a>
<div style="{$post_visibility}" id="post_{$post['pid']}">
