Divi Not compatible

Hi, I tried to use this plugin for Divi theme and I got this error:

Fatal error: Uncaught Error: Call to undefined function et_is_ab_testing_active() in /data/web/virtuals/86955/virtual/www/subdom/new/wp-content/themes/Divi/includes/builder/framework.php:64 Stack trace: #0 /data/web/virtuals/86955/virtual/www/subdom/new/wp-includes/class-wp-hook.php(298): et_builder_load_modules_styles(”) #1 /data/web/virtuals/86955/virtual/www/subdom/new/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(NULL, Array) #2 /data/web/virtuals/86955/virtual/www/subdom/new/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #3 /data/web/virtuals/86955/virtual/www/subdom/new/wp-includes/script-loader.php(1221): do_action(‘wp_enqueue_scri…’) #4 /data/web/virtuals/86955/virtual/www/subdom/new/wp-includes/class-wp-hook.php(298): wp_enqueue_scripts(”) #5 /data/web/virtuals/86955/virtual/www/subdom/new/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(NULL, Array) #6 /data/web/virtuals/86955/virtual/www/subdom/new/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #7 /data/web/virtuals/86 in /data/web/virtuals/86955/virtual/www/subdom/new/wp-content/themes/Divi/includes/builder/framework.php on line 64

Any ideas to solve this? Thanks
