Well, I just learned a very hard lesson. All of this time I’ve never bothered to make a backup of my site before installing updates. And, finally, it happened. Something broke during an update. Luckily, I have my site set up to backup automatically once month. So, I didn’t lose everything. But I did lose over 2 weeks of posts.
So, over the next few weeks I will be rewriting some of those, now gone, posts.
I think I’ve learned my lesson though. From now on, I will always make a fresh backup before installing anything.
