I was supposed to upgrade my All in One SEO Pack plugin to the latest 1.6.4 version, but it’s not the usual one click upgrade.
Perhaps it’s because I upgraded from the older version of 1.5.6 to the latest version. The Upgrade Options button was not there and there’s a need to back up the database first.
To back up the database, I must click on a button there. I was freaked out because I was worried that I would mess up the database and lose the whole site.
Look! I am not that Internet savvy, okay? 
Instead of backing up the database, I decided to deactivate the plugin temporarily and go on updating my blog with some latest insurance quotes found online.
Perhaps I will wait until my blogging pal has upgraded hers and let her guide me.
