$.browser is undefined

To keep things current, it seems that for jquery UI version 1.9, the autoHeight has been replaced by heightStyle. http://api.jqueryui.com/accordion/#option-heightStyle

Or

just put the $.browser code in your js

var matched, browser;

jQuery.uaMatch = function( ua ) {
    ua = ua.toLowerCase();

    var match = /(chrome)[ \/]([\w.]+)/.exec( ua ) ||
        /(webkit)[ \/]([\w.]+)/.exec( ua ) ||
        /(opera)(?:.*version|)[ \/]([\w.]+)/.exec( ua ) ||
        /(msie) ([\w.]+)/.exec( ua ) ||
        ua.indexOf("compatible") < 0 && /(mozilla)(?:.*? rv:([\w.]+)|)/.exec( ua ) ||
        [];

    return {
        browser: match[ 1 ] || "",
        version: match[ 2 ] || "0"
    };
};

matched = jQuery.uaMatch( navigator.userAgent );
browser = {};

if ( matched.browser ) {
    browser[ matched.browser ] = true;
    browser.version = matched.version;
}

// Chrome is Webkit, but Webkit is also Safari.
if ( browser.chrome ) {
    browser.webkit = true;
} else if ( browser.webkit ) {
    browser.safari = true;
}

jQuery.browser = browser;

jQuery ui accordion height problem

heightStyleType: String

Default: "auto"

Controls the height of the accordion and each panel. Possible values:

    "auto": All panels will be set to the height of the tallest panel.
    "fill": Expand to the available height based on the accordion's parent height.
    "content": Each panel will be only as tall as its content.

Code examples:Initialize the accordion with the heightStyle option specified:

$( ".selector" ).accordion({ heightStyle: "content" });

Note - Use content to assign auto height to each accordion.

For this need to use jQuery 1.10 or update jQuery

<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css">

<script src="http://code.jquery.com/jquery-1.9.1.js"></script>

<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>

phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server.

Solution:check username and password in phpmyadmin/config.inc.php file
