I have created a website in 2 different languages using the multisite option and the plugin multisite language switcher. I have opted for a multisite installation with subdirectories. I've first installed and created my wordpress website locally on my laptop to be able to work offline and now the website is ready, I just tried to transfer it to my new hosting provider Justhost and made the appropriated changes to wp-config.php... but I still have an "Error establishing a database connection". I've checked my database and connect it through phpmyadmin and other tool, my credentials are good. Can anyone help on this particular problem?
Thanks so much in advance.
