For those who cannot see added bans, check if mysqli is running.
I was playing around with it a few days ago and left it enabled, yesterday
i saw that all saved ipbans were gone (not showing in list).
it took me quiet some time to find out that
config.php
PHP Code:
$config['Database']['dbtype'] = 'mysqli';
caused it..
PHP Code:
$config['Database']['dbtype'] = 'mysql';
.. and everything is fine
