Registration problems with personalised profile

I have just set up a new forum, and as per my other two forums, have set up a few personalised profile obligatory questions to be answered when joining.

Unfortunately, although there is a blank space for members to insert an answer, there is no question, and instead there are a load of squiggles?

See the forum here, if you attempt to register and accept terms, you will see what I mean.

Did you change the skin & see if the problem persists?

Yes we have changed the skin numerous times, still same problem.

The skin we used is the standard version, same as our other forums, all we have done is changed the colours.

Ah ha, dont worry, we sorted it, the text is white on a white background.

Duh!
