[ERROR] Redirect Loop!

Hello, thank you for your contribution.

But unfortunately I encountered error that say “Redirect Loop!”.
My site in HTTP is
http://www.access-c.jpn.org/
and in HTTPS is
https://secure1943.sakura.ne.jp/access-c.jpn.org/

I clicked the TEST page link it was shown as https://secure1943.sakura.ne.jp/access-c.jpn.org/?page_id=4. But the page http://www.access-c.jpn.org/?page_id=4 is appear insecure mode. Any help?

I’m sorry that I’m not good at writing in English.
