Hello,
When I load a WP site running xtheme in IE 11 or Firefox on a Windows machine all CSS formatting is lost. The only way to add formatting is to enter the CSS inline. The site looks correct on Chrome and Safari on Mac.
I have also tried adding the following to the functions.php file (didn’t help):
add_action(‘wp_head’, function(){?>
meta http-equiv=“X-UA-Compatible” content=“IE=11” [I had to remove the (<) the beginning and the (>) at the end to get it to show in this message]
