This error has already been faced by a lot of people, but I could not find an answer in my case. My wordpress website works perfectly in local

What I have done:

  • Upload with filezila
  • Create a sql database in OVH -Import all the SQL tables from local to the website with phpmyadmin
  • Modify the wp-config.php file and also the wp-config-sample.php writting my informations.

Thanks for your help !!

  • Right now it's a localhost link. Do I need to change with the real website name?

  • Can you change the name wp-config.php and enter the DB credentials in the installation wizard to see if it will connect? Don't finish installation, just check DB connection.

  • I already modified the wp-config but it didn't work, I get this error. Maybe the localhost is wrong though. The host is OVH. I tried mysql5-21.

I too had faced the same issue many times but after refreshing the browser it solved my problem.

Kindly check the wp-config file and verify if the database name and other information is correct.

Another thing you can try is restarting your local host.

  • I've already done all this but thx
