Latest BackWPUp Update Hung, Now My Site is Down

WordPress “white screen of death” can have several reasons. To fix the problem, usually FTP access is required.

– In some cases the reason can be seen if you enable error-output of WordPress by configuring define('WP_DEBUG', true); in wp-config.php, backup wp-config.php before changes.

– To get more detailed errors, add this line before WP_DEBUG config in wp-config.php like this, backup wp-config.php before changes.

error_reporting(E_ALL); ini_set('display_errors', 1);
define( 'WP_DEBUG', true);

– Sometimes it can also help to delete the plugin-folder (download the folder first to have a backup), in your case /wp-content/plugins/backwpup/

– Sometimes the file .htaccess has been messed up, here the content of a default .htaccess file:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

– Some plugins write to wp-config.php, compare with wp-config-sample.php if any bigger portions are missing, backup wp-config.php before changes.

Greetings, Ov3rfly, and thanks so much for responding. My host provider discovered the error for me (when I double-checked whether it was a billing issue). Here is the solve:

Looking over the php_error.log for your site I am seeing the following error over and over:
[08-Mar-2013 18:41:49 UTC] PHP Fatal error: Class ‘CustomAdminSubPage’ not found in /mnt/stor9-wc1-dfw1/652629/659423/www.martavictoria.com/web/content/wp-content/themes/Inspiration-WP-Theme-v.1.0/inspiration/functions/admin_options/AdminPageFactory.php on line 11
This is pointing to the theme that you are using which is causing the problems. I moved the theme out of the wp-content/themes/ directory and placed it within the wp-content/ folder. This is now allowing the WordPress Dashboard to load where you can reinstall the theme or choose another: https://www.martavictoria.com/wp-login.php
