How can i redirect from https://www.example.org/conference/id to https://www.example.org/conferences in .htaccess
There is a lot of ways about making that. Here is one:
Creating a conferences.php file then create a folder "conferences" and a file id.(html) or (php). Open the id.php and paste this code
header('Location: /conferences');
if you want to use .htaccess, just add this:
RewriteRule ^conferences/?$ conferences/id.php [L]
