Hello,

We've upgraded our Commerce from early 13 to latest 13 version. Everything seemed to have gone well, but when we browse through the episerver back office, all icons are not loading in. This seems to be the only issue occuring afte the upgrades.

-----

EDIT::

We've narrowed down the update that causes the icons to not load in by starting from the beginning and hopping updates (from early 13 to current 13.30.0). The following nuget update step causes this:

EPiServer.Commerce.13.30.0 -> EPiServer.Commerce.13.31.1
EPiServer.Commerce.Azure.14.0.19 -> EPiServer.Commerce.Azure.14.0.20
EPiServer.Commerce.Core.13.30.0 -> EPiServer.Commerce.Core.13.31.1
EPiServer.Commerce.UI.13.30.0 -> EPiServer.Commerce.UI.13.31.1
EPiServer.Commerce.UI.CustomerService.13.30.0 -> EPiServer.Commerce.UI.CustomerService.13.31.1
EPiServer.Commerce.UI.ManagerIntegration.13.30.0 -> EPiServer.Commerce.UI.ManagerIntegration.13.31.1

The issue occurs on all localhosts (not tested yet in online environment). The issue occurs on all browers tested.

We've reviewed the dev tools and found the following contentlink errors returned on the network calls for the icon(s):

We've also checked the Shell.zip file and confirmed the icon images exist. 
In the css file, the url for the background image that is the icon is present and matching with the shell.zip file structure.

Since this issue only occurs on the back office of episerver and only happens with episerver 'native' icons, I would like to start this topic in hope for a fix or some direcitons.

Edit notes:: We've narrowed down the issue to the commerce upgrade. (updated topic to mirror this). We are now trying from the bottum up which commerce version upgrade is causing this issue. Any assistance is very much apreciated as we would like to go to the laters 13 version of commerce.
