Hi,
@southpaw3229
Depending your Joomla configuration, the user creation might require a email validation.
At this moment it's not possible to login the user because it has not been activated.
HikaShop read the Joomla configuration in order to know if he can (or not) login the user otherwise it will try to login ; but it is possible that the login made by HikaShop fails (but I don't know what could be the reasons exactly ; I just know that we call the Joomla login function so we can't be sure with the rest of plugins, etc).
@nuevaera
The system plugin "hikashop registration" which redirect the Joomla registration page to the HikaShop one got some errors that should be all fixed now.
We updated the package so you can re-download HikaShop 2.3.4 to get the modifications.
