Missing Menu bar icons in Personas 3.0 after Kernel Upgrade

[Veeramachaneni]

Hello,

When I launch a Flavor, all the Menu bar icons are blank after upgrade to Personas 3.0 SP 19.

If I take the cursor close to any of the boxes, the text of the menu box is displayed like Display or Change or print etc but otherwise they are all blank as shown above. Text buttons, display the text, it is just the icons that are not showing up.

I tried to regenerate the CUA interfaces, reset the CUA as per note 29197, checked the /PERSONAS/STTNGS table. The icons appear in GUI  but not browser. SAP Note health check in the ADMIN is up to date and all Notes are completely implemented and in green. This issue is to all the users and not a few specific users.

We use Microsoft Edge browser

Kernel - 753

Basis release 750 sp008.

What else can I try to solve this issue?

Thanks!

For the benefit of others who possibly face a similar issue, here is the solution from the related support incident:

Your system is running with SAP BASIS 750 SP 08, which is a very old support package.

As a long-term solution, I would recommend rethinking your system update strategy, and to consume Support Packages in a timely manner.
Using the latest SAP_BASIS Support Package will also have the benefit of the new service handler "CL_HTTP_EXT_ITS_2" which is not affected by this issue - See also SAP Note 0002860209 - SAP GUI for HTML: New Service Handler.
- Use the latest SAP_BASIS SP is an SAP recommendation.
    
As a short-term solution, please make sure to update the currently used service handler: "CL_HTTP_EXT_ITS".
This is reasonable due to the error you are facing:
The MIME file to display icons (SAPGUI-icons.svg) will be loaded from a wrong path due to incorrect theming path.
   
To update the current handler ("CL_HTTP_EXT_ITS"), please implement the below SAP Notes and all of its prerequisites via transaction SNOTE:

You say that this happened "after kernel upgrade", but then you mention that there was a Personas upgrade to SP19. Was it both? 

Just asking because upgrading Personas to SP19 will not cause something like losing the icons on the screen. Rendering the flavor happens via webgui / ITS, so in such a case, a kernel or basis issue is suspect. Perhaps clearing the MIME cache may make a difference, at least it's worth trying. Also, try disabling Personas via URL parameter sap-personas-runmode=0 to use plain webgui and see if the problem is still present (which is my expectation).

Based on an earlier similar support case, upgrading the basis SP could help, along with the latest applicable kernel patch. However, in this situation you may want to create a support incident directed to component BC-FES-ITS (not BC-PER) to receive expert advice from the responsible component's support team.
