Hidden form field – not being hidden

Hi,

Just installed version: 5.132.3 and each contact form now has an additional field added which is visible and has the value ‘0’ inside it.

Suspect it is down to this malformed HTML below as the type, id, name and values are all being quoted twice, once with double quotes and once with single quotes.

<input type=”‘hidden'” id=”‘ct_checkjs_cf7_140f6969d5213fd0ece03148e62e461e'” name=”‘ct_checkjs_cf7′” value=”‘0′”>

The page I need help with: [log in to see the link]
