- Added the AUTH credentials in the Drupal admin:
Opensolr Security
- Added /solr to the Solr Path configuration in Drupal admin:
Drupal Opensolr Config
- Uploaded the Drupal 8 Solr version 3 Solr configuration files, using the Opensolr Configuration Control Panel. These are required in order for Drupal to identify the correct Solr index and version.
