At some point, my Twitter Tools stopped updating automatically. I'm running the latest versions of WordPress, Social, and Twitter Tools. Yesterday, I disabled the WP cron-like feature in Social and attempted to set up manual crons, one each for Social and Twitter Tools. My web host is Dreamhost, and I used the Dreamhost Panel to create the two crons. I ran multiple tests, and Twitter Tools didn't update automatically no matter what I did, so I re-enabled the WP cron-like update in Social while leaving the manual crons active, too. Magically, this morning Twitter Tools is updating as it is/was configured: create a new blog post for every Twitter tweet. Intuition tells me that by dinking with manual crons I woke something up in my hosting environment, like maybe I launched the crond daemon which might have been disabled or permasleeped. But I don't know enough about hosting to confirm or deny. Maybe others who know more can investigate and add to the body of knowledge surrounding this much loved duo of plugins.
