我与客户网站有问题。我安装了Yoast SEO插件（我觉得很好），但当我激活它时，会收到很多错误消息（见下文）。
/storage/content/10/104610/mydomain.com/public_html/wp-content/plugins/qtranslate/qtranslate_hooks.php on line 54 Notice: Undefined index: language in /storage/content/10/104610/mydomain.com/public_html/wp-content/plugins/qtranslate/qtranslate_hooks.php on line 55 Notice: Undefined index: language in /storage/content/10/104610/mydomain.com/public_html/wp-content/plugins/qtranslate/qtranslate_hooks.php on line 61 Notice: Undefined index: in /storage/content/10/104610/mydomain.com/public_html/wp-content/plugins/qtranslate/qtranslate_hooks.php on line 61 Notice: Undefined index: language in /storage/content/10/104610/mydomain.com/public_html/wp-content/plugins/qtranslate/qtranslate_hooks.php on line 111 Notice: Undefined index: language in /storage/content/10/104610/mydomain.com/public_html/wp-content/plugins/qtranslate/qtranslate_hooks.php on line 111
我尝试过的每个SEO插件都会出现此错误消息是什么原因导致的，我如何解决它？
