This guide explains why a website may be "broken" or no longer display anything after a password change at the Web Hosting level.

Broken link with the database

When your website, and more specifically a script (CMS, WordPress, Prestashop, or any other application using MySQL databases), can no longer connect to the MySQL MariaDB database or another database, an error message may appear, such as:

• Error connecting to the database
• Database Error: Unable to connect to the database: Could not connect to MySQL
• Unable to establish a connection to the database

Remember your last action…

If an error occurs on your site, always check the recent history. In this case, was there…

1. … did you make any changes to the configuration file of the script in question? Has it been affected, modified, or moved?
   
   Sometimes, the unintentional insertion of a space before or after a word can break the connection between the web server and the database server. Revert your file changes.
   If necessary, restore an older version of the files that you recently modified.
   
2. … an action on the database password in the Infomaniak Manager?
   
   If you change the password for your database via the Infomaniak Manager, then your script, which retrieves its information from the databases, will no longer display anything.Changing something in the Infomaniak Manager means you need to change it everywhere else. This change you made in the Manager also needs to be reflected in the script's configuration file by connecting via FTP and modifying the appropriate file, usually "wp-config.php", "configuration.php", or similar.
   
3. … a server migration announced by Infomaniak?
   
   If this error occurred following a server migration or another operation announced by email and related to the product in question, do not hesitate to contact Infomaniak support.
