Just installed Hikashop and Hikamarket today and during the config when saving receiving error. Please advise

Hello,

Yes, it looks like you had some old data in your database which were not migrated correctly.
I will add a patch in the next release which should be very similar to your own patch you sent via the "contact us" form.
Indeed, we need to make sure that the "vendor_params" is decoded or reset it to an empty object if an error occurred.

Regards,
