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):
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]
My licensed copy of this site is mepseviipatient.mydevelopmentdomain.com, but I do not want to place that domain on the forum, so I created the following test site on a different domain: www.dbvstaging.com - hopefully you will trust this.
Any help you could provide would be greatly appreciated. I would be happy to provide admin access to this test site if needed.
