Remove tutorial video from the Affiliate panel

If you want to remove the tutorial video button from Quick navigation icons of Affiliate panel's Home page, you would need to edit the home.tpl template file.
You would find it at Configuration > Design > Affiliate panel theme > click "Edit theme" on the currently active theme > and look up home.tpl
Click the 'home.tpl' and you will see its code on the right side. From its code remove:
{widget id="Tutorial"}

and click Save. 

Refresh the affiliate panel.

NOTE: if you are trying to edit a default theme (created upon installation of Post Affiliate Pro), the system will claim to create a copy of the theme, because the default themes are overwritten by each update of the application. For more info click here.

Check out the  image below - there is no tutorial video anymore.
