The third-party Moodle themes currently supported by Turnitin's Moodle plugins are Boost and Classic.
If you are integrating with Turnitin via the Direct V2, Plagiarism Plugin, or Integrity Plugin, please ensure your Moodle Learning Management System is using one of these supported themes. Using any other theme may lead to unexpected behaviors, as they are not supported by Turnitin.
If your institution utilizes a custom theme, please opt for the LTI 1.3 integration instead.
If you are unsure of the theme in use, please contact your Moodle site administrator, who should be able to assist you with this.
