1. Download your style here  (you may need to activate your license first) and extract the zip
  2. Upload contents of the /upload/styles/ folder to your /styles/ folder by using your FTP or control panel
  3. Go to your control panel, Appearance -> Styles -> Import, import the style found inside your XML folder
  4. Now click the + Add style button and fill in as followed:
    1. Title: Name Your Style
    2. .Description: Give a brief description of the style (optional)
    3. Important! Parent style: Set the style you imported on step 3 as the parent style
    4. You can set the style to the default forum style by choosing the radio button (highlighted in red below)

Few key points:

  • Do not make edits inside the main style (the one that says (Parent DO NOT EDIT)
  • Any edits you want to make should go inside your child style, in the above example "My Style"
  • You will lose all customizations on upgrade if you customize the style that says (Parent DO NOT EDIT)
