"kill IE6" file generates 404 error

Hi there!

I have this code in the header of every page:

<!–[if IE 6]><meta http-equiv=”refresh” content=”1;url=/home/vg005web09/82/24/3012482/web/wp/wp-content/themes/im-businessmaker/assets/styles/_ie/kill_ie6/ie6.html”><![endif]–>
<!–[if IE 7]><link rel=”stylesheet” type=”text/css” href=”https://www.rightkey.com/wp/wp-content/themes/im-businessmaker/assets/styles/_ie/ie7.css”&gt; <![endif]–>
<!–[if IE 8]><link rel=”stylesheet” type=”text/css” href=”https://www.rightkey.com/wp/wp-content/themes/im-businessmaker/assets/styles/_ie/ie8.css”&gt; <![endif]–>
<!–[if IE 9]><link rel=”stylesheet” type=”text/css” href=”https://www.rightkey.com/wp/wp-content/themes/im-businessmaker/assets/styles/_ie/ie9.css”&gt; <![endif]–> <!–[if lt IE 10]><link
rel=”stylesheet” type=”text/css” href=”https://www.rightkey.com/wp/wp-content/themes/im-businessmaker/assets/styles/_ie/ie.css”&gt; <![endif]–>

As you can see, the first one has a different path from the others, and that line is generating lots of 404 errors. I don′t know where to change to make it look like the rest, or how to simply remove that line from the code. Any ideas? I use a custom theme, but there′s no reference of this subject in their support site.

Thanks in advance. Regards!
