WordPress for Joomla Error

So it is that code is not always perfect, yep sorry to trash that house of cards which was your reality of the technology industry up until now! Recently when logging into a Joomla site in which we have WordPress for Joomla installed, we were seeing some errors pop up. While these have hot shown any functional problems, it was more an irritation, like having a fly in a car (which is much better than having a bee in a car, as highlighted in this cartoon by The Oatmeal).

The error being displayed took the form of something like the following (modified to protect the innocent directory structures):

Warning: in_array() [function.in-array]: Wrong datatype for second argument in /./././components/com_wordpress/wp/wp-includes/widgets.php on line 728

So a little searching and I found the result that I needed on the CorePHP website forum, as it would seem that this issue had been seen by some other unfortunate before us!
