I would like to change labels , hide some tabs(tabs like Terms&Conditions for Vendor or URL for Product Add etc.) on Product Add or Vendor Manage pages.
I was able to find where it comes from , for vendor page it is companies.php under controllers/backend directory hwoever when I duplicate the file under /app/addons/my_changes/controllers/backend/companies.php it returns Service Unavailable for that page.
When I tried companies.post.php , it doesn't return any error even , page doesn't load at all.
