I have put on my page.xml a new block for add my minify magento scripts to the bottom.
<block type="page/html_head" name="javascript" as="javascript" template="page/html/javascript.phtml">
<action method="addJs"><script>scripts.js</script></action>
</block>
And in my template just before </body>
:
<?php echo $this->getChildHtml('javascript') ?>
It's perfect and scripts.js load now to the bottom.
But I don't understand because when I load scripts.js to the bottom nothing works correctly on my frontend and if I move to the top it's perfect...
Thanks for your help.
