Can not register as a new user or login as a guest

-- url of the page with the problem -- : 108.174.152.219/~yamitysb/index.php/hika...out/step/step-1.html

-- HikaShop version -- : 2.3.1
-- Joomla version -- : 3.3
-- PHP version -- : 5.3.28
-- Browser(s) name and version -- :
-- Error-message(debug-mod must be tuned on) -- : Error_message

Can not log-in as a guest or register as a new user on check out.
The buttons (הרשמה = register , guest) are not linking.

Do I need to do any integration with Joomla log-in module or any other kind of integration.
Attached are two images with the Checkout setting.

Please advise
Thanks

Hello,
I think that the issue is coming from your template, can you test it with one of the default front-end Joomla template ?
Thanks.
