so i had a sub domain i dont use anymore, once i deleted it, the folder still there when i connect via FTP, is there any way to delete such a folder? ofc i dont have permision to do so
That depends on how recent the subdomain was added. If it’s this year, you should be able to delete it like you delete any other folder. If it was created before, there is sadly no way to delete it.
I tried but have no permission to delete on the root directory, i made the sub domain this year.
