假设您的登录凭据正确，请尝试使用此选项，然后通知我-

var $log_path = 'C:\\wamp\\www\\livesite\\logs';
var $tmp_path = 'C:\\wamp\\www\\livesite\\tmp';

$log_path与数据库无关，您需要检查$dbtype、$host、$user、$DB和$password。您到底遇到了什么错误？先生，我遇到了Internet服务器错误，实际上我必须为我的网站更改joomla verion..并且无法与数据库建立连接..@user2123036检查您的凭据以及日志和临时路径是否正确设置..同时检查是否意外出现任何空格$dbtype、$host、$user、$db和$password，我检查了很多次，没有发现任何错误….$log_path='/wamp/www/livesite/logs'；var$tmp_path='/wamp/www/livesite/tmp'；
