It seems you made more changes in the WordPress installation and Apache is throwing this error message in its error_log file
[Mon Feb 25 15:04:53.704106 2019] [proxy_fcgi:error] [pid 12166:tid 139626903729920] [client 188.8.131.52:59890] AH01071: Got error 'PHP message: PHP Parse error: syntax error, unexpected '*', expecting end of file in /opt/bitnami/apps/wordpress/htdocs/wp-config.php on line 88\n'
When checking the line 88 of the wp-config.php file I found this:
* Absolute path to the WordPress directory. */
You will need to change that line to be like this one
/** Absolute path to the WordPress directory. */
Let us know if you can access the application after applying that change
