Install a theme

Add a MyBB theme by importing its XML and uploading its assets.

A MyBB theme is usually a theme XML (colours and templates) plus a folder of images/CSS. Install both.

Import the theme XML

  1. In the ACP, go to Templates & Style → Themes.
  2. Under Import a Theme, upload the theme's .xml file and import it.
  3. Set it as default, or let members pick it under Configuration → Theme.

Upload the theme's assets

  1. Connect over SFTP or open the in-panel file manager.
  2. Upload the theme's image/CSS folder to the path the theme specifies (often under images/).
Blank or broken styling almost always means the assets didn't land in the exact folder the theme expects.
