I have done asper directed by my webhost manager. following the instructions of this website: Use Cloudflare’s SSL certificate on your site. And did the folloing instructions from the website:

1 Under the SSL/TLS menu, enable one of Cloudflare’s SSL options.

1 Wait for the changes to be available on your site.

2 Install and activate the Cloudflare plugin.

3 Install the Cloudflare Flexible SSL plugin to avoid running into Redirect loop issues in your dashboard.

6 In your Cloudflare settings, create a Page Rule to redirect all traffic from HTTP to HTTPS.

I have miss step number 4 and 5 according to the instructions on page:
Use Cloudflare’s SSL certificate on your site.

Because I have no idea where this code suppose to go. Either on Cloudflare or my webhost?
