Is had an issue that I as Superadmin could edit every product, by someone (say product editor) else that has only the access level to edit product could save the product or when switched to a variant product she needs to login again.
First, I thought that has to do with sessions variables. But couldn't find it. Then I made the product editor account also Super Admin account and did the test again. On that moment the product editor still gets logged out although Superadmin not.
Next step was checking the differences between both accounts. And it seems that the editor was different. Superadmin had Editor JCE and the product editor the default editor (was, in this case, AcyMailing Editor). After setting de default editor to Editor JCE, everything was working well.
It seems that AcyaMailing Editor is not working with Hikashop.
My problem is solved, and I hope that this could also help other users.
