I closed this topic before noticing the following. I noticed that et-core plugin was not activated, and when I tried to activate it, I get the following error:
Plugin could not be activated because it triggered a fatal error.
Fatal error: Cannot redeclare initial_ETC() (previously declared in /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/et-core-plugin/et-core-plugin.php:424) in /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/et-core-plugin-old/et-core-plugin.php on line 423
