Missed Schedule for Posts in WordPress

As I started queuing the posts for the previous run of “Ready for 2010“-articles, I came across a problem with my WordPress installation. The scheduled articles didn’t show up when they were scheduled, and the only thing shown in the WordPress administration interface were a message about “Missed Schedule”. No shit, sherlock.

The reason behind the message is that the wp-cron.php file didn’t run as it should. WordPress usually tries to run this every now and then by inserting a reference to the file through the web site. Apparently this behavior was borked on my blog. I have a perfectly working cron implementation on my server, so instead of relying on WordPress to do some kind of magic to insert a reference to the file and kick off the processing with a web request, I added a reference to wp-cron.php in my usual crontab.

I have no idea how often wp-cron really should be run, but decided that a five minute resolution was enough for my use. The crontab entry is included here:

*/5 * * * * cd <directory of blog> && php wp-cron.php

This runs the cron script from the proper directory, and seems to work fine.
