Hi,
I can’t edit my website theme in my production server, but it works great in my developement server with exactly the same versions of frappe/erpnext (checked with git log), the same databases (backup restore) and the same user (Administrator).
Here is the screenshot with the production server on the left and developement environment on the right. In the production server, I don’t have the blue Save button on the upper right, neither the link box for bootstrap CSS and so on.
Regards
