I changed my SQL password through my webbhost. After that I found out that I couldn't enter my website anymore. I'm 99% sure it has to do with the login credentials. So I was searching around on the internet and found the
define('WP_ALLOW_REPAIR', true);-code but that didn't helped me. I also tried to replace the following in my
define('DB_NAME', 'database-name'); define('DB_USER', 'database-username'); define('DB_PASSWORD', 'database-password');`
Another strange thing I found out is there is 2 folders. One
wp-config.php and another one where all the credentialinfo is called
wp-config-sample.php. Maybe it doesn't matter. Is there anyone who had a similar problem and fixed it or someone who could help me?
