  • Open F12 developer tool to check the traffic trace, there are many ERR_ABORTED or 404 Not Found error within files under icmandir, below shows some of the example error log:

    net::ERR_ABORTED 404 (Not found) 

    https://hostname:port/sap/public/icmandir/its/lsgui/js/its_frameset.js?xxx
    net::ERR_ABORTED 404 (Not found)

    caught ReferenceError: owguDOM is not defined
        at Frame.create..

Notice in this case WebGUI alone doesn't work. The error message might be different when calling WebGUI alone than when it's called from FLP.
If webgui alone works, then it's not covered in this KBA.
