Hallo,
welchen Fehler haben Sie genau?
Genau den gleichen wie der Herr vor ein paar Monaten?
"Site off-line
The site is currently not available due to technical problems. Please try again later. Thank you for your understanding.
If you are the maintainer of this site, please check your database settings in the settings.php file and ensure that your hosting provider's database server is running. For more help, see the handbook, or contact your hosting provider.
The mysqli error was: Access denied for user '1_testuser'@'localhost' (using password: YES)."
