Hi!

After updating a week or two ago (after the security update), I installed php-mcrypt on my CentOS node.  I also (for good measure, added the disable command (below) in the config.php. Restarted Apache, cleared cache, used multiple browsers, etc  ... I still get the following notice/warning at the top of the screen when I log in. 

Observium now requires mcrypt to be installed for use by the "remember me" function. Please install the php5-mcrypt package on Ubuntu/Debian or the php-mcrypt package on RHEL/Centos. Alternatively, you can disable this feature by setting $config['login_remember_me'] = FALSE; in your config.
