我正在尝试导入 WordPress 的演示数据——我收到如下错误：
Error: Internal Server Error (500)
这是日志文件：
"The import files for: Zox News Demo Import were successfully downloaded!
Initial max execution time = 30
Files info:

Data file = /var/www/html/wordpress/wp-content/themes/zox-news/import/zox-news.xml
Widget file = /var/www/html/wordpress/wp-content/themes/zox-news/import/zoxnews.wie
Customizer file = not defined!

谁能告诉我如何解决这个问题？
