I am experiencing this exact same issue.
The reCaptcha preview under BWP reCAPT shows perfectly but when I add the reCaptcha short code to the form (only one form on the site), it doesn’t show when viewing the page. http://lq-creative.com/contact (re-capture is positioned just above submit button).
WP 3.5 (multisite but i’m only using the primary site at the moment)
bwp-recaptcha installed, activated and public / private keys correct
contact-form-7 installed, activated and tested – all ok
contact-form-7-bwp-recaptcha-extension, 0.8 installed & activated
Please, help me get this working.
Many thanks,
Tim
