Try this, in header.php:
Code:
<?php
if (is_page(1)) {
echo "<meta http-equiv="X-UA-Compatible" content="IE=8" />";
}
?>
This should work but unfortunately sometimes doesn't work for me while it's worked for others.
The number 1 you see will be your page ID. All you need to do to get the page ID is go to your list of pages, and put your cursor on the "edit" link and you'll see the page ID in the URL which is displayed in your status bar, at the left/right hand side of the screen. Replace your ID with that one and you should be set.
