Hi
I have searched the forums for an answer to this. This error occurs both in newest Hikashop 2.0.0 and also the most current version previous to that.
The shop is a Joomla! 2.5.8, Hikashop 2.0.0 and it has one custom field:birthday
This is a textfield, for the user table, required and it is set to appear everywhere (frontpage, controlpanel, listing and it is active), see screenshots.
I also has activated the plugin "HikaShop joomla user account link plugin". See screen shot.
This is what happens: A user registers and has to enter a birtday, a javascript makes sure of that. The birtday is stored in the table, I can se that happens (with the use of PHPMyAdmin).
A link is sent to the user to confirm the account and email. After the user clicks the link in the email, the data in the custom field birtday is gone. The custom field is emptied by the user clicking the link in the confirm account email.
Also, if I turn off the plugin, there is no difference. The custom field is emptied then too.
This is not so good, we can't open the store without this information about our customers.
