Hi,
We recently reinforced security in the backend. So by default only super administrators have access to the HikaShop configuration (already the case before), emails, mass actions, views, and custom fields.
If you want administrators to also have access to these, you need to go in the Joomla configuration page, access the HikaShop options page:

There, and under the permissions tab, add the "Configure ACL & Options" access to the administrator user group:
