Cart Empty after login from registration

-- url of the page with the problem -- :
-- HikaShop version -- : 2.2.3 Business
-- Joomla version -- : 3.2.1
-- PHP version -- : 5.3.10
-- Browser(s) name and version -- : Google Chrome
-- Error-message(debug-mod must be tuned on) -- : NA

I have added some products to cart, then I have registered an account through regular registration, then activate by email. Then my cart is empty, is there any way to fix it?

I have activated "HikaShop user synchronization plugin"

Any other reasons?

Thanks

Now my setting is
Session Lifetime: 15
Session Handler: Database

What should I change?

It is the same, but you may try once here

Thanks

Yes, once I disabled the SSL, it works now

So everything is ok?
If so, thanks for sharing your solution

Yes, it is solved ~~~

Now, I generated with a new SSL which is more relevant to my sitename, it works very well.

I have same problem, add things to cart, after that loguin and cart is empty.
Or go to order process and when I reach payment page it says, empty cart

(J 2.5.22 /HikaShop Business: 2.3.2/ php 5.3.28 ) but I can't find the synchronazation plugin!!

Also my site is ALWAYS on https:

The full name of this plugin is "HikaShop user synchronization plugin", you can find it and enable it via Joomla Extensions > Plugins. Be sure that you don't have filters on the listing to see this plugin.

If you still don't see it, thanks to try to re-install HikaShop over the current install.
