I have deployed a ASP.net website and for whatever reason the website is rendering like it should on the web server, but when i access it from a client some of the formatting is lost, so for instance the menu items disappear from the menu, i am at a loss as to where to begin as the website is functional, it just isn't rendering how it should, i suspect that it might have something to do with CSS, but really not sure.

I have tried to make remove some reference to bundles and called the style sheets directly using link with no difference.

I have checked i am able to access the site.css from a client too.

Having looked a bit further into it, IE is returning the following two errors:

SCRIPT5007: Unable to get property 'createElement' of undefined or null reference jquery-3.3.1.min.js (2,6997)

SCRIPT5022: Bootstrap's JavaScript requires jQuery bootstrap.min.js (6,31)

  • hmm, that is strange, it renders fine in Chrome, just not working in IE – bradonline Jul 08 '19 at 15:27

    IE has different rendering modes that can be utilized. You can read about that [here](https://stackoverflow.com/questions/6771258/what-does-meta-http-equiv-x-ua-compatible-content-ie-edge-do). – mason Jul 08 '19 at 15:29

Have you checked the mime type registered on iis? It could be possible that the response for the css request could have a different mime type than what the browser expected and thus did not parse it/apply the style rules. To check/fix this, open server manager -> browse to your site. In the IIS settings panel would be Mime types, ensure that text/css is the MIME Type for the .css extension, also in your link tag try including type="text/css" as well.

Thanks guys, managed to figure it out, the issue was there was a GPO setting that was ticked to display intranet sites in compatibility mode, i unchecked this and it began to work as expected, hope this helps someone else.
