[Plugin: jQuery-Pagebar] Problem with URLs

In jQuery-Pagebar 0.3.2.1, when you have an URL like this:

http://example.com?something=foobar

the plugin creates this URL:

http://example.com?something=foobar?paged=5

which should be

http://example.com?something=foobar&paged=5.

There is a simple fix that should solve this problem for good:

In jquery_pagebar.php,

find this code (line 148):

if(get_option('permalink_structure') != "") {

	if (is_search()) {

		$loc_href =  '\''. $url .'&paged=\'+ ui.value ;';

	}else {

		$loc_href =  '\''. $url .'?paged=\'+ ui.value ;';

	}

} else {

	if (is_search() or is_archive()) {	 

		$loc_href =  '\''. $url .'&paged=\'+ ui.value ;';

	} else {

		$loc_href =  '\''. $url .'/?paged=\'+ ui.value ;';

	}

}

and replace it with this:

if ( false === strpos($url, '?') )
	$loc_href =  '\''. $url .'?paged=\'+ ui.value ;';
else
	$loc_href =  '\''. $url .'&paged=\'+ ui.value ;';
