My domain uses cPanel, and Softaculous is available in it.
I want to set up a WordPress blog. In the set-up page, under Database Settings, what do I put in the box for Table Prefix, or can I just use the value given in the box? What is Table Prefix, and can I change it after setup?
You can choose any random characters and add "_" at the end or you can also leave the one that is suggested by Softaculous. If you would like to change it later you will have to manually change the prefix for all the tables in your database and also change it in the wp-config.php file on your server.
