Hi,
As you can see through our official Live DEMO:
demo.flexiblewebdesign.com/fashionmart/index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=34&Itemid=477
ReCaptcha is not being appeared in the "Ask a Question" form. Because this is a new feature and was presented recently in Virtuemart. Therefore, this new feature should be implemented to our templates as well.
When FashionMart is updated, this feature will definitely be added, for sure. (it is possible to show reCaptcha in some of our templates though, such as: CleanMart)
For now, you may disable the FashionMart stylization and use the official layout of Virtuemart Component on "Ask a Question" form page, so you should start seeing the reCaptcha then.
To disable the FashionMart stylization on "Ask a Question" form page... through FTP, rename this folder:
/templates/YOUR_TEMPLATE/html/com_virtuemart/askquestion/
to
/templates/YOUR_TEMPLATE/html/com_virtuemart/askquestion2/
and you will start using official virtuemart layout on ask a question form page.
Regards,
Support
