Apologies to anybody who has been getting a front page of the web log looking a little like this picture.
The source of the problem is a bug in the version of WordPress that runs the site, that up until now has only been a problem for people running blogs on certain server configurations. However it seems that somebody has discovered a way to trigger the bug, and based on the discussion here has, in much the same way as the spammers send repeated comment spam, has hit multiple WordPress weblogs around the world.
Thankfully there is a solution to the problem, so I’ll put that in place as soon as I can. Prior to the fix, if you encounter the problem click here and then click ‘Back to Blog’ to fix the issue.
