I have at least 10 domains on DH running Joomla. After I performed the most recent upgrade (using 1-click), I discovered a number of my directories are no longer writeable, as Joomla expects. So while everything currently seems to be running fine, I cannot upgrade any components/modules/mambots or do any new installs of other extensions.
I checked at least 5 of my domains, all under different FTP users and found this situation to be true for all of them. AND, the number of unwriteable directories differs from domain to domain. I also inspected domains where I am NOT running Joomla and found no directory problems there. So I am currently suspecting the 1-click upgrade script is missing some essential code to properly set ownership after it has done its work.
I’ve logged a support ticket, but I am curious to know if anyone else has discovered this problem too.
