Thanks for the reply!

Here's the master configuration file:

    var $editor = 'tinymce';
    var $list_limit = '20';
    var $helpurl = 'http://help.joomla.org';
    var $debug = '0';
    var $debug_lang = '0';
    var $sef = '1';
    var $sef_rewrite = '1';
    var $sef_suffix = '0';
    var $feed_limit = '10';
    var $feed_email = 'author';
    var $secret = 'tkWWMADlQ60dF4YW';
    var $gzip = '1';
    var $error_reporting = '0';
    var $xmlrpc_server = '0';
