First: thank you for your reply.
What exactly you want to change some footer text or key?
It is not that.
It is that: 1. text_footer, 2. text_footer_left and 3. text_footer_right
are all 3 inside admin/controller/common/footer.php
Then if you go to the admin, only text_footer and text_footer_left show up as editable
but not the third one text_footer_right. So it is a logically thought where to find
text_footer_right in the Admin just like the other two. But it is not there in the Admin.
It looks to me that text_footer_right is somewhere hardcoded in abantecart
