Once logged into your DirectAdmin control panel, please navigate to Softaculous Auto Installer under the Extra Features section.
In the top left-hand side search bar, please type WordPress and click on Wordpress when you see it appear. This will bring you to the WordPress installer's main page.
Click on the Install drop-down menu and click on Quick Install and complete the Software Setup.
If you are looking to install WordPress on your main page, please make sure the "In Directory" box is blank. Most times you will need to remove the "wp" from this box.
Once you have set the Admin username, password, and email address please scroll down and click on Install
