XenForo is already installed in your database
This means that the database you selected (u584811126_xenforo) already contains XenForo data.
Because of this, you have two options:
Option 1 – Fresh installation (delete everything)
- Check the box:
- “Remove all XenForo-related data, including posts and users”
- Click Begin installation
- This will permanently delete all existing XenForo data (users, posts, settings).
Option 2 – Keep existing forum data
- Do not check the box
- Do not continue with the installer
- Instead, you should use the upgrade process or simply fix your config.php file to connect to the existing installation
