Hi,
I'm working on some fixes for the registration in HikaMarket.
I see that the migration of the user registration function into HikaMarket had some loses.
About the vendor image during the registration, you can see to replace
if(!empty($this->element->vendor_id) && hikamarket::acl('vendor_edit_image')) {
into
if(empty($this->element->vendor_id) || hikamarket::acl('vendor_edit_image')) {
it should work (but it require some tests).
I'll see to add an option into HikaMarket, it will be easier.
For the password, HikaMarket uses the option "registration_ask_password" ; the password is not link to the HikaShop setting.
The simplified registration in HikaShop is link to the guest checkout ; so I preferred to not plug HikaMarket on it.
I should have a working package in the next hours. I have to finish my tests and add some options.
If you can provide me an access to your backend I can see to update it directly in your website so you would be able to tell me if all is good.
Regards,
