white page with user registration redirect plugin

-- url of the page with the problem -- : www.lacasettabio.it/component/users/?view=registration
-- HikaShop version -- : 2.3.4
-- Joomla version -- : 2.5.27

Hi,
Yesterday a user gave me the notice that he could not be able to register to my site.
The problem is that if the "Hikashop Registration Redirect Plugin" is enable i have a White page.
If i disable the "Hikashop Registration Redirect Plugin" it works but i have the joomla fields but i need the hikashop user fields.
The link to register to my site is :
www.lacasettabio.it/component/users/?view=registration
Could someone help me please?
Thanks
regards

In JOOMLA global configuration on tab Server, change Error reporting to maximum, save changes, then try to open your link again.
If there is Fatal error, download latest version of Hikashop and update.
Don't forget to change Error reporting back to none.

Hi Korzo,
yes i had a fatal error.
I installed the last version of Hikashop again and now it works!!!
Thanks so much!
But it was my fault or it was something wrong on Hikashop?
Thanks for your help

Hi Jerome,
yes you're right!
I'm sorry, excuse me.
Regards
