Troubles with images and css after migration to the new server

This could be many things. You'll want to first start by using the developer tools with your browser and find out what errors your page is showing. From there you can start to make fixes.

First issue I find is the server is not set to allow the proper MIME types. In this case, your fonts might not load, specifically the .eot and .woff2 fonts.

You'll want to check disk permissions to ensure the user running the application pool has at least read access to the website root directory.

Are you sure you copied all the files? There's a good chance some may have been missed or not copied properly.

Where are your design files (images, css, js, etc.) located? Do they have absolute URL paths referenced or are they relative?

Hi Vasyl,

As rightly said by Brenden, there could be multiple reasons. Would you mind sharing a screen shot of developer console to see what all errors are appearing there?

Thanks Chetan

all files were copied, there are no absolute url.

IIS_IUSRS has full permisions to the foldder.

As a temporary fix we added permisions for Everyone and this fixed our problem.

But i still don't understand why IIS_IUSRS full permisions don't work
