System Failure when customer should be redirected to paypal

-- url of the page with the problem -- : dswrights.com/index.php/hikashop-menu-for-products-listing
-- HikaShop version -- : 3.2.1
-- Joomla version -- : 3.8.2
-- Error-message(debug-mod must be tuned on) -- : System failure

see above. I don't know what I did wrong installing the extention, but when a customer shoudl be redirected to paypal it shows a system failure.
It seems like the information needed isn't transferred.....

Hi,

I couldn't test. I had to create an account, and for that I had to click on the confirmation link sent to me by email, but I never got the email.
Please provide a working test user account so that we can try.

Hi, that's another problem then, how can I fix the problem with the email?

Hello, I've decided to remove the module. Thanks for your time.

Hi,

If you don't have the emails sent by your website, you probably have an issue with how you configured the email settings of the Joomla configuration. You would have to check with your hosting support.
However, a simple solution is to turn off the new account validation setting of the Joomla user manager.
