(I am new to all of this, so pardon stupid questions)
I have made the changes to the "wp-config-sample.php " file and saved it as "wp-config.php ". I then uploaded everything.
This was successful.
I checked with my server to make sure that I had the MySQL set up correctly on their end, and that I had the username, password, and database name correct.
But now, when I try to "Launch /wp-admin/install.php in your browser." --that is, when I put into the address bar: " my domain name.org/wordpress/wp-admin/install.php" (and I have tried leaving out the "wordpress" file name) I just get a "the page cannot be found" window in my browser.
Also, regarding the "wp-config.php " info, am I right that if my database name is Parmenides, the info in the file should look like this?:
