Introduction
The dxpr website is currently based on Drupal 7 and it's a collection of custom modules, as well as a slew of contributed modules. The wysiwyg setup and blog content type are based on our CMS profile but there is not much left of the original configuration of that profile.
If we do a major update of the website, we'll develop it from scratch on Drupal 9. For now we'll have to make do with Drupal 7.
