Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.
The module uses Libraries API now, so after upgrading to v1.2, you need to download Easy Responsive Tabs to Accordion plugin and copy it to "sites/all/libraries/easy-responsive-tabs" folder. See project page for details.
