If you want to change the URL’s site you can use wp-cli. You have to go to de directory of your WordPress page and run this command.
wp search-replace http://domain.com https://domain.com/portal --dry-run
If you are sure, try the instruction without –dry-run. If you get this error:
mm:fame.ec mario$ wp search-replace https://www.fame.ec http://www.fame.ec –dry-run Error: Error establishing a database connection.Change in wp-config.php localhost for 127.0.0.1
