If you’ve upgraded to WordPress 2.2 and use the latest K2 theme you’ve probably noticed some oddities. On stuff.za.net only the header loaded, a temporary fix was go back to an older version of the K2 theme.
After a quick search I found the cause of the problem, its the Sidebar widgets. Turns out that the code that K2 use for the sidebar widgets and a new feature in WordPress 2.2 are slightly incompatible and this ends up breaking everything. But as usual someone else has got a fix, just took me a few minutes to find and apply.
You need to download and install this plugin which when activated disables K2’s widgets. As usual let me know if things appear broken or don’t work properly.
