Unable to register

I recently updated my Hikashop to 1.5.0 on 5/11 and I just found out now that users are no longer able to register. When they try to register, it redirects them to the front page. I tried downgrading to 1.4.7 again and the problem is still there. How do I fix this? www.alcachofaampolletas.org

I uninstalled Hikashop and reinstalled, and now people can register, but it clears the cart upon registration. How can I fix this?

There was indeed a glitch in the first builds of the 1.5.0 version. It has been fixed since then and installing the latest build (so you need to redownload it from our website) should solve the problem. I just tested on our demo website and it works fine.

I do have the most current build installed, but it still clears the cart upon registration (I downloaded it just a couple hours ago)

Which version of joomla are you using ?
Please check that the system plugin hikashopuser is published and that in the plugins/system/hikashopuser.php file you have the line of code:
if(empty($cart) && !empty($this->cart)){

The plugin hikashopuser was not published. Publishing that made it work. Thank you so much!

Joomla 1.5.22
The line of code was in hikashopuser.php
