I have just bench updated my server and noticed on red line in the update which is Error: EACCES: permission denied, open ‘…/…/sites/assets/frappe/css/email.css’
I have been trying to set the email in my erpnext and it always fail… could this be the issue?
No your issue is different. The email.css is simply a graphic style sheet. But this file will need to be chown or chmod on your install.
It’s a bit odd you have only one file with incorrect permissions. Did you do some editing of this file separately ?
I have never done the editing on mail file
