[TYPO3] mailformplus multipage ssl

[Simon Browning]

I've got a multipage form that we've created using mailform plus which 
works very well, unless we enable ssl.  Under ssl we never get past the 
first page of the form, it just reloads itself.

Looking at the debug output, it doesn't look like the form is picking up 
any of the field values (see below).  Any assistance/boots in the right 
direction would be appreciated.

Thank you.
