after spending some hours with this issue I now dare to ask. I think I have overseen something stupid. After switching in production mode my, I run static content deploy command wich runs without any errors. But after that admin and frontend are missing all styles. Seems although deploy command works, static files are not written, pub/static is missing files and console error says require.config failed to load. strangely, I seem to have the opposite problem of those who have in the developer mode problems with the symlinks, because the developer mode with the symlinks works wonderfully, the symlinks are written without problems in pub / static.
