HELP! Tried to update, and can’t get blog back

With index.php I’m getting this error message:

Fatal error: Call to undefined function: is_admin()in /homepages/26/d212929719/htdocs/Creation/wp-includes/vars.php on line 16

Can someone walk me through how to fix this????

Hi Kedda,

If you are calling your site from https://www.yourdomain.com then you need this index.php in your root on the server:

<?php
/**
 * Front to the WordPress application. This file doesn't do anything, but loads
 * wp-blog-header.php which does and tells WordPress to load the theme.
 *
 * @package WordPress
 */

/**
 * Tells WordPress to load the WordPress theme and output it.
 *
 * @var bool
 */
define('WP_USE_THEMES', true);

/** Loads the WordPress Environment and Template */
require('./wp-blog-header.php');
?>

If your files are in a directory called blog (or something else) but you still are accessible from https://www.yourdomain.com change the last line to: require('./blog/wp-blog-header.php');

If you are working from https://www.yourdomain.com/blog then the full index shown first here should be in the directory blog.

I’m not understanding something simple, I’m guessing. I tried your suggestion. I have my blog in a directory called Creation. [I have another blog in a different directory on the same server]

I tried changing the index.php to the above script, with require(‘Creation./wp-blog-header.php’) and then tried require(‘.blog/wp-blog-header.php’) and both times got this new error message:

Fatal error: main() [function.require]: Failed opening required ‘.blog/wp-blog-header.php’ (include_path=’.:/usr/lib/php’) in /homepages/26/d212929719/htdocs/Creation/index.php on line 17

clicking on function require brought me to the error 404 (not found) message. I still need help!

Also, I tried putting the index.php in the root directory, and in the Creation directory. In the root I get the 403 error message, Forbidden!

I know that there is something simple I am missing, but I don’t know what it is!

I tried changing the index.php to the above script, with require(‘Creation./wp-blog-header.php’) and then tried require(‘.blog/wp-blog-header.php’) and both times got this new error message:

no period after Creation in your first try

just Creation/wp-blog-header.php

Well… after trying to fix the update problem, I finally deleted most of my newly uploaded files, and then re-loaded a newly downloaded older version of WordPress that I had been using, figuring it was clean, and got my blog back again. I don’t know if I’ll ever try updating again! At least I knew I had my database backed up, so I could get my posts back again at some point.
