Today we found great way to detect absense of markup or HTML attributes in developer tools of Internet Explorer (IE).
All we know that markup in DOM-tree may be changed after page load using JS-scripts. So, all you need to understand root cause of absense of markup is check whether all required files are loaded.
To get this information, just:
1. Open developer tools in IE
2. Open “Network” tab
3. Click “Start capturing”
4. Refresh required page and then check result of file downloads
if you get 40x errors, pay attention to this case it may be your resolution.
