Doug,
Can you explain what you mean by "Replace hikashop login with JFBC"? In general, you have a few options if you want to add our buttons to your page. You can:
* Add the SCLogin module to your site wherever you want the buttons to appear
* You can use various plugins to redirect a login page to the standard Joomla login page, which should show the social login buttons
* You can add the {JFBCLogin} tag to your module's layout files wherever you want the social login buttons to appear.
I hope that helps explain, but if not, let us know. Also, please post from the account you subscribed to JFBConnect as priority support is for active subscribers only.
Thanks,
Alex
