Hello, Thank you for the taking the initiative to develop Opigno. As an eLearning Developer I am very excited of this possibility. I am able to install Opigno, and the modules needed. However, as soon as I try to enable the modules in Drupal's module manger, I get HTTP 500, or blank white screens. I have uninstalled and reinstalled Drupal and the modules many times to figure out how to handle this. I am new to Drupal, but to lower the possibility of the HTTP 500, I have been paying attention to the listed "module requirements" prior to enabling individual modules. Is there an action plan in which order to enable Opigno's list of module components (with checkmarks), and its other required modules that need to be installed? What am I missing here? A video tutorial will be extremely helpful. Please forgive the novice questions. Kindly refer me to any reading materials I need. Thanks again.
