 * Using LearnDash 2.4.4 and Uncanny 2.0.5. Topics Autocomplete Lessons is activated.
   When a user finishes his course, the following error appears:
 * Warning: Invalid argument supplied for foreach() in /wp-content/plugins/sfwd-
   lms/includes/ld-groups.php on line 1300
 * If I deactivate the Topics Autocomplete Lessons feature, the error dissapears.

 * Hi Arturo,
 * We tried to replicate this but haven’t been able to see it in our environment.
   Have you tried with all other plugins besides LearnDash and the Toolkit deactivated?
