Showing reCaptcha in the ask question has been added after a while VM2.x was released. We have included this feature to CleanMart after it was introduced on Virtuemart.
Most likely you still using an old version of CleanMArt.
The solution is;
- Get the new version of CleanMArt;
- Copy this folder from the new CleanMart installation package: /com_virtuemart/askquestion/
- upload/overwrite this folder on your server to here: Root/templates/YOUR_TEMPLATE/html/com_virtuemart/askquestion/
then you will start seeing the reCaptcha. Another solution is;
rename this folder:
Root/templates/YOUR_TEMPLATE/html/com_virtuemart/askquestion/
to
Root/templates/YOUR_TEMPLATE/html/com_virtuemart/askquestion2/
which will disable the CleanMArt stylization from ask-a-question popup (you will start using the official Virtuemart layout) then reCaptcha will be printed.
