Updated Server from 11.2(MU2) to 11.2.1.
Now some icons in the console are lost: in the browser they show as "../zenworks/images/appIcons/69817_11e0c707743eaa425b164c21795170de.abc"! But this should be png-files.
If I rename one of them back to ".png" I can open this normally with a image-viewer.

Anyone else with this problem? Any suggestions? (Beside replacing all corrupt icons )
