  • Relevant error message is:

    Elgg couldn't connect to the database using the given credentials. Check the settings file.

    The credentials you provided aren't working any more. Your database changed location or the username/password are not correct. Double check that you configured it correctly.

    Is this a new installation or an existing site?
