The following work for me as expected, trying to connect to a configured phpmyadmin installation:
http://localhost/myphpadmindir/ #connecting from the host itself http://myhost.mydomain/myphpadmindir/ #connecting from any other host http://localhost/myphpadmindir/setup/index.php #connecting from the host itself
but the following just hangs and never returns (does not show login page)
http://myhost.mydomain/myphpadmindir/ #connecting from the host itself
This is phpmyadmin 4.1.0, MySQL 5.6.15, Apache/2.2.24 (Unix), PHP/5.4.17, MacOSX 10.9, mysqli, any browser (tried several).
No error messages are shown in any logs.
