Prerequisites for using the ilos Button plugin for Atto:

  • Access to the server where Moodle is installed and running. As this plugin is not registered for automatic update, it cannot be upgraded from Moodle UI and requires direct access to the server.
  • The Atto rich text editor for Moodle. This may be enabled by navigating to Site Administration > Plugins > Text editors > Manage editors on the left-hand column of the Moodle page and using the up/down arrows to move 'Atto HTML editor' to the top of the list. Make sure that Atto is enabled by confirming that its corresponding icon under the 'Enable' column shows an unobstructed eye, or click the icon until it appears this way.
