Hello,
1) I don’t see any redirect to blog page one visiting the home page https://gyazo.com/4793cf55a37840abd37e0bcdb7c652da
2) I suppose that you lost your header and theme options because you restored DataBase that did not have correct theme settings or your hosting provider did not restore get_theme_mod. In this case you need to go to Theme Options > Header builder > create correct header and save it. Do the backup of your settings in Theme Options > Import/Export > export settings and use it once you need.
Regards
