I got exactly the same error with Joomla 4.3.3 on MAMP localhost

in configuration.php , you have to change the variable $host it fixes the problem

Hi Erik, I've the same error.
Could you please inform what should I change the variable $host with?
Thank you very much

[erick-b]

public $host = 'localhost';

[ForTheCinema34]

public $host = 'localhost';

Hi Erik,
thank you for the information, but in Configuration.php the parameter is already set like "Localhost".

I hope to find another solution.

@ForTheCinema34, it is not a good idea to post to other topics, which will confuse the issues and make understanding the circumstances more difficult. That is why the forum rules do not allow cross posting.

The Original Poster (OP) of this topic decided to restore the Joomla 3 version. The website is up and running and I have now marked also this topic as resolved.
