Could not autoupgrade from inside the site admin area. Had to manually update the files as per instructions on website.
Most every plugin still works – I think. If there are any oddities, please inform here so that I can fix it up.
Still yet to update this forum (currently Simple:Press Forum 3.1.4) which is now an ageing old build. Many administration features in the forum ceased to work about 2 wordpress upgrades ago. Definitely didn't work with 2.8.2 anyway.
Upgraded Simple:Press Forum from 3.1.4 to 4.2.0 today.
As a reminder, I need the full package with additional skins and icons set. Otherwise, this forum just looks bare with bad formatting.
Haven't had time to test if everything works yet – the website host (by 3ix) is a little unstable at the moment. Server load is high and spam daemon is down – maybe the server has received a real heavy load of spam recently?
