For some reason, automatic WordPress upgrades are not working on this server.
The upgrades for both WordPress core and Jetpack did not work from the Dashboard. I instead had to download and do the upgrades via FTP.
After that, a theme upgrade did work from the Dashboard.
This system informed me that an automatic update (3.8.1) has been installed on this system.
Whether you like it or not, this is kind of a killer feature that takes care of one of the biggest problems out there in the WP world: out-of-date systems. There are all kinds of people running WordPress, and not all of them are keeping as close an eye on their installations as they might. These automatic upgrade go a long way toward keeping those systems safe.
If you’re the kind of person who’s really on top of things, this might be welcome, or an annoyance. But there are more people than you know who just aren’t getting in there and doing the updates when they should.
My guess is that something with the devio.us server made it difficult for me to update this site’s WordPress software to version 3.8. I failed in a number of attempts in the past month or so. But today I was able to do the update, and now this site is fully patched.
I suspect that the devio.us admins made a change/fix. However it happened, it’s nice to have an up-to-date WordPress installation.
