I have no clue what fsckopen and cron are and how they work, but I am disappointed at the resolution of trac #3565. Perhaps the folks who closed this ticket have root privileges on their PHP, their DNS and their servers. I don't. I don't even have access to my /etc/hosts and crontab...!
The simple reality is that, once I upgraded from 2.0.x, scheduled posts do not appear in my blog.
This is not a DNS bug, people. It's not a server config bug, either. It's a WordPress bug.
Wow, my life was okay up until 2.0.11.
Do you guys have any workaround or suggestions? Note that I cannot edit my crontab.
