I'm sorry but in PM there is not anything to upload file, also in contact us section, please give me an email

Hi,

You can send a mail at contact@hikashop.com
Don't forget to write a clear subject and give a link of that topic in the body of the email.

Hello,
the file we have sent you is the only that collects PHP errors. If you need a real time monitoring, we can enable you display error parameter.

Kind regards,

I'm copy/pasting here my answer for everyone else:

I found the error:
PHP Fatal error: Call to undefined function acymailing_get() in
/plugins/hikashop/acymailing.php
on line 42, referer:
index.php?option=com_hikashop&ctrl=checkout&task=step&step=4&Itemid=118

That means that you have a really old version of AcyMailing which is
not compatible with HikaShop. You will have to either update
AcyMailing or unpublish the HikaShop Acymailing plugin via the joomla
plugins manager.

yes, upgrade the module resolve the problem, thank you !
