Invalid address: mailer->addReplyTo

Hello I found after updating latest Joomla to 3.5.1 that new user can not get reply confirmation email to his inbox and it shows "0" error page now found.
The user is gathered by registration in SQL but it not send back confirmation email to user it can be activated.

The reason is some php mailer functions needs to be updated.
Please check this URL I found: http://joomla.stackexchange.com/questio ... omla-3-5-1 and tell me how can I fix this.

Thank you.

Hi, so I fixed this issue by myself.
So if anyone have this issue and you are using Hikashop OR some extention that redirect Joomla Registration to Hikashop or to your extention, please update latest version and you will be good to go
The issue was in my side Hikashop but the strange thing is that I did not know that Hikashop has new update, in my case 2.6.2 as in my new updated Joomla 3.5.1 it doesnt show new update available, so I thought I have latest Hikashop 2.6.1, but it wasnt true actually.
So I downloaded manually from Hikashop website and uploaded package and it is working now.

Cheers

Hi

Yes, joomla 3.5.1 as brought a small change to the mailing function and components which are based on that function will break. Gavick has developed 2 extensions which were affected: GK Registration and GK Contact. Both has been fixed and can be found in rest_files packages for Your template.
