Having an SSL certificate installed doesn't automatically redirect visitors away from the unencrypted http:// version — that needs to be configured separately.
- Open File Manager in DirectAdmin and locate the
.htaccessfile in yourpublic_htmlfolder. - Add a redirect rule at the top of the file that sends http:// traffic to https://.
- Save the file and test by visiting the http:// version of your domain — it should now redirect automatically.
Not comfortable editing .htaccess directly? Most SEO and caching plugins for WordPress include a one-click 'Force HTTPS' toggle that does the same thing.
