当我尝试安装mediawiki 1.22.1时，它会在mediawiki网址上引发以下错误
Catchable fatal error: Object of class Language could not be converted to string in /home/hackep6t/public_html/mw/includes/Exception.php on line 722
但奇怪的是，如果我再次尝试访问相同的网址，则会显示已安装的mediawiki。如果我关闭窗口并重新打开它，那么它会再次显示错误。请帮忙。

现在它抛出这些错误消息：

我有完全相同的问题。我通过在.htaccess中禁用eaccelerator来修复它：
php_flag eaccelerator.enable 0
php_flag eaccelerator.optimizer 0
我认为这是eaccelerator中的错误。如果您使用其他优化程序，请尝试禁用它。因为mediawiki的代码在异常回溯中提到的行中似乎没有错误。
