After some initial problems with my personal blog, I almost dare not touch the upgrade button. However, I read that Pablo has problem getting into his WordPress at Delicious Asian Food and though he did not confirm if it is hacking, I am very, very afraid of it. My sites have been hacked into previously and I am not going to take any chance.
Then, I had some chats and I heard that it is very, very easy to hack WordPress! Wooo…that got me into action immediately. So, with fingers crossed, I had upgraded a few blogs to WP 2.2.1 already.
This blog now runs on WP 2.2.1 and you better get yours done too. This time, I have no problems with my wp-config.php file anymore. But to be on the safe side, remember to backup all your files first. Follow the step by step provided by WordPress.
