Fatal Error on Wordpress: Call to undefined function wp() in wp-blog-header.php

Question

I updated Wordpress to 4.2 this morning, and now I can't access my Wordpress site, gteam.org.

I've searched the Wordpress help forum, but to no avail.

Thoughts or help:

Fatal error: Call to undefined function wp() in /home/team1874/public_html/wp-blog-header.php on line 14

Answer 1

我遇到了同样的错误，问题是我的 wp-config.php 文件不知何故是空的，只是复制了示例 wp-config 并添加了我的配置，然后它又工作了。

Answer 2

I met the same problem this morning when trying to install wordpress v4.9.4 . The most likely reason is that the file which declared function wp() is somehow damaged. I solved it reload a new package and installed.
