I tried to migrate my MySQL installation to a new server. Both new and old servers are in the same intranet.
Tried many times to change the wp-config.php file to new server but no avail and it always fail with ” we can’t contact the database server at localhost”. However, clean new installation works.
It seems WordPress is always stuck at “localhost” database no matter what the
DB_HOST content are. This also occurs in another existing installations. Please help.
