Symbolic links to other directories are not specifically set up.
WP_CONTENT_DIR and WP_PLUGIN_DIR are not customized in wp-config.php In other words, they are left as default.
WP_CONTENT_DIR : /home/bitnami/stack/wordpress/wp-content
WP_PLUGIN_DIR : /home/bitnami/stack/wordpress/wp-content/plugins
The original error dialog I saw stated “DirectoryIterator::__construct(/bitnami/wordpress/wp-content/plugins/simple-lightbox/includes/class.options.php ):”, so I thought there was a configuration discrepancy in Simple Lightbox or in our WordPress itself.
Is there something I need to set in wp-config.php?
