Custom theme does not load
We are facing an unusual issue on our Fiori Launchpad. We have created a custom theme using the Theme Designer. This theme has been transported into our QA and PROD boxes using /ui5/theme_tool. We have also defaulted this theme for all users using the parameter THEME from transaction /UI2/NWBC_CFG_CUST.
Now when a user logs in, a weird screen is shown to them instead of the theme that has been defaulted. The screenshot of this is attached. The Http trace shows the library.css file is not loading for some reason.
However, once the user goes into User Preferences and chooses the custom theme, it loads properly. It continues to load correctly even after the user logs off - so the issue is only for the initial login.
I have an SAP incident open but whenever SAP logs in using the WTS that has been provided to them, the theme loads properly. We have also tried a bunch of server side cache clearing reports(below) as well as clearing the cache of the browser but nothing has helped.
Any ideas @Masayuki Sekihara?
