Sidebar error

[ciccio79]

Hello everybody.
Since yesterday this code appears at the top, on the homepage of my forum.

');var sidebar_align='right';var content_container_margin=parseInt('290px');var sidebar_width=parseInt('270px');

I state that I have not changed anything. It suddenly appeared.
Disappears when I disable the sidebar.

How can I solve it?

To quote Lynne.

What are you using on your server that is adding "pagespeed.jm" to all the links:

')<!--[if lt IE 8]><link rel="stylesheet" type="text/css" href="css.php?styleid=1&amp;langid=1&amp;d=1446084785&amp;td=ltr&amp;she et=sidebar-ie.css" /><![endif]-->

Try disabling that. Above is where the code problem is. So, something is putting it there.
