/opt/bitnami/apache2/conf/bitnami/bitnami.conf file, you have removed the VirtualHost on port 80. Please restore it.
Then, on your
wp-config.php I see that you have made many changes. For example, you removed this lines, which are probably causing your site to load incorrectly:
define('WP_SITEURL', 'http://' . $_SERVER['HTTP_HOST'] . '/');
define('WP_HOME', 'http://' . $_SERVER['HTTP_HOST'] . '/');
Please, add them back to the file after this block:
* The WP_SITEURL and WP_HOME options are configured to access from any hostname or IP address.
* If you want to access only from an specific domain, you can modify them. For example:
Restart the servers and check again. If something is wrong, please share a new Bitnami Support code again.
