can you check your browser console for JS errors while running the wizard and copy/ past those here miksa93?
Hi, this is the error (running it this time it got stuck on the first part of step 2)
load-scripts.php?c=0&load[]=jquery-core,jquery-migrate,utils&ver=4.9.7:4 POST http://ntchrvatska.com/wp-admin/admin-ajax.php?_fs_blog_admin=true 504 (Gateway Time-out)
send @ load-scripts.php?c=0&load[]=jquery-core,jquery-migrate,utils&ver=4.9.7:4
ajax @ load-scripts.php?c=0&load[]=jquery-core,jquery-migrate,utils&ver=4.9.7:4
n.(anonymous function) @ load-scripts.php?c=0&load[]=jquery-core,jquery-migrate,utils&ver=4.9.7:4

r.handle @ load-scripts.php?c=0&load[]=jquery-core,jquery-migrate,utils&ver=4.9.7:3
this is the relevant part;
POST http://ntchrvatska.com/wp-admin/admin-ajax.php?_fs_blog_admin=true 504 (Gateway Time-out)
so there is _a_ request (possibly AsyncJS’s) that is timing out on the server. this _could_ be due to a plugin that uses Freemius (as per the _fs_blog_admin parameter), so have a look at which plugins use Freemius and try disabling that/ those while trying the wizard?
