Redeclare get_temp_dir() error

Error: Fatal Error: Cannot redeclare get_temp_dir() (previously declared in /home/public_html/wp-includes/functions.php:2160) in /home/public_html/wp-admin/includes/file.php on line 189

Solution: Reinstall all WP core files. To keep the plugins, themes and content. Just deleted WP-Admin and uploaded the fresh version and the same for the functions.php.

Blank Page

If you see a blank page it could be because the installer had wrong info or something is missing in htacces, this default htaccess could also help with people logging and wp permalinks working correctly

WP-Config Editing

There is several other things you can edit in the config file but for this purpose or any database errors you would want to look for the following things within your wp-config file.

// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'Database-name');

/** MySQL database username */
define('DB_USER', 'Database-username');

/** MySQL database password */
define('DB_PASSWORD', 'Db-password');

/** MySQL hostname */
// Depending on your host you may have a different local host name or a remote hostname that you would need to provide
define('DB_HOST', 'localhost');

Default Htaccess

make sure the following is in the htaccess file in the same folder as the folder with wordpress in it. Also depending on the version you may require different information in the htaccess file which you can refer to the source link. Source: http://codex.wordpress.org/htaccess

# 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

Manual Theme Changing

Source: http://docs.appthemes.com/tutorials/how-to-change-wordpress-themes-directly-from-the-database/ Another part of the issue is changing the template manually to something else.

This first part checks for the theme

SELECT *
FROM wp_options
WHERE option_name = 'template'
OR option_name = 'stylesheet'
OR option_name = 'current_theme';

Then you can use that information to then change the template by using this following command.

UPDATE wp_options SET option_value = 'Template Name' WHERE option_name = 'template';
UPDATE wp_options SET option_value = 'templatename' WHERE option_name = 'stylesheet';
UPDATE wp_options SET option_value = 'templatename' WHERE option_name = 'current_theme';

Worst case scenario you set them back to a default template

UPDATE wp_options SET option_value = 'Twenty Eleven' WHERE option_name = 'template';
UPDATE wp_options SET option_value = 'twentyeleven' WHERE option_name = 'stylesheet';
UPDATE wp_options SET option_value = 'twentyeleven' WHERE option_name = 'current_theme';
