In case you didn’t notice the message on top of your WordPress dashboard, WordPress 2.8.6 is now available. The release fixes two security problems that can be exploited by registered and logged in users with posting privileges.
Basically if you have untrusted users on your blog with a user level of “Author” or above, upgrading is highly recommended.
I’m sure you know the drill by now, make sure you backup before you upgrade. I haven’t heard of any upgrade issues with this release so it should be relatively painless.
Looking for web hosting?
Question: What's the best type of web hosting?
Answer: The kind you don't have to worry about.
And that's precisely why I recommend HostGator. I've been using them myself for years and they've been nothing short of superb.
Fast load times, great support, WordPress-friendly, and good prices. Not much more you can ask for.
New customers can get 25% off of any HostGator web hosting package with the coupon: themelab25percentoffNote: I am a HostGator affiliate, but that doesn't make my recommendation any less genuine.
