Hi,
Sorry about that; we have not yet updated that wiki article for our x10Hosting Basic theme. I took a quick look at your account, and it appears you have created a MySQL database, but have not yet created your MySQL user. Please choose "Databases" at the top of cPanel, and click the cog next to your database. Choose "Manage Users".
Please click "Add User to Database" in the top right. From there, you can specify your MySQL user's username and password.
Next, you will be prompted to choose some "privileges" for your newly created user. Please check "Grant All Privileges" and click "Update Privileges".
You can then use "
localhost" as your MySQL Host in MyBB, and the username/password you have just created for the credentials. The table prefix can be whatever you choose, such as "
mybb_".
Please let me know if you have any further questions.
Thank you,
