Tried everything to delete these sites and the one bench, please let me know how to achieve this
I face the same problem today (December 19, 2023)
Site is broken (it never created properly) but there’s no way to drop it.
Opened a ticket at https://support.frappe.io and await support.
Well, after maybe a couple of hours, the Drop Site button appeared in my case. I was able to delete the site yesterday.
I’m not sure what made this happen. One possibility is browser cache. The other is frappe support staff actually did fix something in the cloud to make it available.
