Can I turn off technical domain of the shop?
The technical domain of the shop, in the form of login.offerer.com is required for the proper operation of the shop and it is not possible to disable it. It is a service identifier and enables emergency login to the panel in case of problems with the assigned main domain of the shop.
The technical domain of the shop is not normally visible to the customer, does not index in the search engines, nor does it double the indexed content thanks to the canonical links mechanism.
