I'm new to use of SSL. I'm running a forum based on PHPBB3 and I'd like to implement SSL so that users are always under HTTPS when using the board. I know it might sound odd because its quite inusual to see a forum under SSL, but some of the private sections of it contain sensitive data.
Back to the point, I've googled to find an answer but nothing worked until now. Could someone write me a brief walkthrough with the steps I should follow?
Note: I already have an installed SSL certificate in cPanel server.
