For some days, WordPress has been showing me that an update is available.
In fact, it shows 3 updates are available. So let’s click on “Updates” in the Dashboard and find out what they are and see how to deal with them.
Before we do anything in the update section, it is very advisable to backup your blog. Luckily, WordPress reminds you to do this:
The first update available is WordPress 3.0.1, which I can either download or update automatically.
The second update is for a the Contact Form 7 plug-in.
And finally there is an update for the TwentyTen theme.
My usual method of using automatic updates is to process the plug-ins first, and then do the WordPress update. But the TwentyTen theme presents me with a new problem, because I’ve modified it. I may want the update, but I also do not want to lose my modifications.
Anyway, to start with I’m going to upgrade the Contact Form Plug-in.
The update enables maintenance mode and a few seconds later has completed the update.
At this stage, return to WordPress Updates.
For the time being I’m going to leave out the Theme update, and just update WordPress. However a complete WordPress installation will overwrite the TwentyTen directory, so either make a copy of the directory first, or update manually using FTP (I’ll cover that another day).
The blog goes into maintenance mode, which can last a couple of minutes.
But otherwise the update worked for me.
Except that TwentyTen was reset.
So I copied my modified files back into the directory and everything was OK again.
Obviously I don’t want to have to do this every time, so I’m either going to have to permanently move my modified TwentyTen theme to a different directory, or investigate something called “child themes”. These are both options that I will be looking into in the future.
