After having all 4 of my websites hacked because of WP 2.8.1 (at least that is what my host told me) I'm unsure if I should keep using it. I use WP as a CMS for most of my clients, and I can't risk having their sites hacked because they haven't upgraded to the latest version of WP yet.
Was this just a one time slip up with WP? Or should we fear that future versions might lack security and can be hacked again? I just need some reassurance that I can continue using WP for myself and my clients without having to keep constant watch on the upgrade versions. I thought I was on top of upgrading, but just one day too late cost me my sites.
What do you all think?
