Your self-written script or the just installed CMS does not run as expected or a blank or white page is displayed? We have compiled the most frequent sources of errors for you.
Error in CMS configuration (WordPress, Joomla etc.)
A common source of errors are incorrect or incomplete information in the configuration file of the CMS.
Example 1: Wrong database name in the wp-config.php of a Wordpress installation.
define('DB_NAME', 'dbo123456789'); define('DB_USER', 'dbo123456789'); define('DB_PASSWORD', '123456789'); define('DB_HOST', 'db123456789.db.1und1.de');
Error analysis: This part of the configuration files contains the access data of your database. Instead of db123456789, the database name was not entered under DB_NAME, but the user name dbo123456789. This causes the error message "Can't connect to database" when Wordpress is started.
Example 2: The same error as in example 1, but this time in the configuration.php of a Joomla installation.
public $host = 'db123456789.db.1und1.de'; public $user = 'dbo123456789'; public $password = '123456789'; public $db = 'dbo123456789';
AuthType Basic AuthName "Passwortgeschützter Bereich - Nur für geladene Gäste" AuthUserFile /kunden/homepages/12/d123456789/falscherpfad/.htpasswd ErrorDocument 404 /404/fail.html
Error analysis: There is no.htpasswd file in the /wrong path/ folder.
