我的Wordpress网站突然显示了以下内容：

天气晴朗了大约3/4天，现在我明白了。我甚至无法登录到管理端查看。。。有人能告诉我正确的方向吗？我对PHP不太感兴趣。
谢谢。
您的主题是填充
你可以尝试直接在数据库中用程序改变主题
UPDATE wp_options SET option_value = 'default' WHERE option_name = 'template';
UPDATE wp_options SET option_value = 'default' WHERE option_name = 'stylesheet';
UPDATE wp_options SET option_value = 'default' WHERE option_name = 'current_theme';
希望你能登录。在生产
此处唯一的问题是array_unshift()错误。剩下的信息就是这样的结果。因此，只需要修复array_unshift()问题。
但不确定是什么原因导致了这条消息，wp-content/themes/contrast/themolution/includes/theme-functions.php中的line 37上有什么？？
