Hi All,

Syracuse 12.19 will be fixed this issue. Please check with Support Team see if the hotfix can be delivered. 

At this moment, to resolve this case with a workaround which is just to remove the 2 menus from the Administration page. The menublock "Notification" can not be deleted as it is a "Sage factory " item

• Open the "Administration/Authoring/Pages/Navigation pages
• Edit "home" page
• Click on "Administration" module, it will open the administration page of this module
• Click on "Collaboration" sub-module
• In items, you should see a "Notification" block. Edit the sub-module. Remove the menu items inside the "Notification" block and save. 
• The sitemap should be displayed normally for all users at their next logon.

Hope it's helpful!

Thank you Claudia, are you saying that these two blank entries under Notification are causing the issue and should be removed? Is there understanding on why these are causing the whiteout/blank menu issue? 

Having gone into the Navigation menu and not making changes, and then coming out of it by clicking the Sage logo, it triggered the white screen. I logged in with another browser and deleted those two entries and it worked. I then went into another folder and went into the navigation menu and after coming out of it the white screen came back. I added an item to that Collaboration menu, and the problem was again resolved. I'm wondering if a change has to be made in every folder? Also, it seems like making a change was the key, rather than simply deleting the two blank items (or perhaps a combination of both?). Anyway, this is just information, more than a question. Thanks!

Alternative way (this is done on a Sage X3 v12p31 instance):

From MongoDB Compass, in `syracuse`, look for `MenuBlock` with filter to code: `S_COLL`.

I had this same experience.  v12 p33.
