variation products and cache problems

Hi, I found a really wiered problem.
Everytime when I add the variation products my site turned down.
I can’t access to my wordpress admin page, it says it has a redirect loop.
I have to clear my browser cache in order to get it in to the admin page.

I have no idea why this is happening.
It worked fine if I just have simple product tho.
I have tried to delet all the plug-in, and this still hapeening so I believe its not
plugin problem.

Does anyone have the same problem?
I have tried to fix it in many way but it still there..

thanks
