Error message when trying to post a review.

I am trying to leave my karcher steam cleaner review and I can't. Everytime I click on preview or post I get this message:
java.util.HashMap$Values cannot be cast to java.util.List

Is it something wrong on my end (laptop has just had brain surgery) or is it MN going wonky?

Hi there,
Sorry to hear about this Feijoa. We've just had a go ourselves and all fine and dandy. Perhaps your laptop should still be in intensive care? All good wishes.
Seriously, have another go when you feel your laptop is up to it, and get back to us if you still have a problem.

Hi FVS, it looks like there might be a problem our side after all. We'll take a look.

What ever you did it's fixed now and my review has been posted. Thank you.
