why can't my blog be displayed using iframe while other people's blogs can please explain.

Question

Answer 1

When the parent page is encrypted using SSL, the iFrame must also point to a URL using the HTTPS protocol.
NOTE: It appears you're web page shows a warning when using https:
https://avirahman.info
You may be referencing other files using http instead of https on your default page.
Try replacing http:// with https:// in your iframe code as well.

Answer 2

There seems to be something wrong with SoloLearn. I put this code in my browser and it's working fine.

"You may be referencing other files using http instead of https on your default page." how is that, this is my personal blog to learn as far as I know, there are no free ssl and how to avoid warning in my blog

Answer 5

Directing to http from https can cause this warning. Sololearn uses https, your site does not.
