Thanks Liam.
I have done some further searching on the internet and came across a note from Droidbox.

Not sure if they are connected in anyway to EBox but here is the link:

Essentially, they have a similar problem on their Home Page which was caused by an issue with Yahoo Weather.
That was back in April and there hasn’t been an update on the link since.
Their immediate solution was to recommend the creation of a custom launcher and use a different widget.
Bit drastic, I think. Not sure why they didn’t just change their own widget.
