I have tried migrating site to a testing environment. There are a few problems:
1) manger can not clear the cache consistently - sometimes the window remains open, but sometimes it is successful. This is an old problem and not 2.2. related.
2) manager can not flush sessions: flush_sess_err ... Same as above
3) having cleared the cache manually (otherwise you get Could not find action file at: controllers/default/welcome.php as in documentation), now I get another message: Could not find action file at: controllers/default/index.php. There is no tree on the left but tabs (Resources, Elements, Files) is there. Have re-checked core/config/config.inc.php. Any ideas about this?
4) after this I re-ran the setup. In install log there is exactly the same stuff as in my first post
