I’ve taken the plunge and upgraded WordPress and at the same time changed themes, upgraded plugins etc. And, bar a few fiddly errors, it went pretty smoothly. One word of advice for others lagging on really old versions of WordPress – take the time to upgrade version numbers one at a time (major stable version by version) rather than jumping straight to the latest – it saves a lot of pain.
I hope the new look makes posts a little more readable and navigable.
A number of readers who have been lumbered with SOEs (standard operating environment) that still insisted on an outdated version of Internet Explorer were complaining that the last redesign left them unable to read all the comments on longer posts should now be happy too.
