Infomaniak Releases Guide for WordPress Database Connection Issues

Infomaniak has published a new guide in its knowledge base aimed at administrators of WordPress websites. The guide addresses the frequent "error establishing a database connection" issue that occurs when WordPress fails to connect to its database. This problem can arise, for example, following a change in a web hosting plan.

The new guide aims to clarify for users how to update the settings in their WordPress site's wp-config.php file to match new database connection details. The guide specifically outlines which three key pieces of information โ€“ the database name, the host server, and the username โ€“ need to be checked and updated.

Emphasis is placed on that, in most cases, the solution involves updating the prefix for the database name and username to align with the new format. Infomaniak also provides links to separate guides for establishing an FTP connection and locating the necessary MySQL information, to ensure a smooth process.

This addition to the knowledge base demonstrates Infomaniak's commitment to supporting its users in overcoming technical challenges, particularly when they are upgrading their services or migrating to new plans.
