Wordpress无法启动-500错误：PHP致命错误：在第14行调用未定义的函数define（）index.php

Question

Error

Wordpress doesn't start - 500 Error : PHP Fatal error:  Call to undefined function define() index.php on line 14

Line # 14 : define('WP_USE_THEMES', true);

it works sometimes, it doesn't work and shows the above error, please help me to find the cause.

Answer 1

This is a tough one to answer without lots of background information, is this perhaps nginx with php-fpm where php can't find the file included in the "require" part that comes at the end of index.php?

require( dirname( __FILE__ ) . '/wp-blog-header.php' );

The above line is at the end of index.php and it eventually includes all the wordpress functionality. If your server cant find that file, and that is where I guess the error comes from.

(Sorry, I dont have enough points to comment, so it had to become an answer).
