WordPress environments hosted on AWS Lightsail experience compatibility issues with Redux Framework v4. It appears that there is a shortcut or symlink between the paths /opt/bitnami/wordpress/wp-content and /bitnami/wordpress/wp-content.
A similar issue is documented in Bitnami’s GitHub repository here.
We recently updated the options framework from v3 to v4. Redux 4 uses the /bitnami/wordpress/wp-content path, which does not match the actual path of the files.
According to the solution provided in the article, to resolve this issue, you only need to add one line to the wp-config.php file:
define('WP_CONTENT_DIR', '/bitnami/wordpress/wp-content');
