I recently split my HTML site in PHP so I can make global changes more easily and get ready for a possible migration to Wordpress. The HTML version works with IE and Chrome. Now that I split the site in PHP it only works in Chrome. In IE a lot of the CSS elemets are missing. Is this a common mistake I can fix? Remember the same HTML code works in IE so it has to be something I am doing wrong in the PHP version. I have the same issue with another website I am working on. Maybe there is a special character I am missing?
