I am trying to upgrade the site to zen 1.5.7. I went to google and selected v2 visible. Received the public and private keys, saved them in the file, uploaded all the contents of the includes folder. Then uploaded the contents of the v-155-only folder. However on my contact page I see the captcha but I don't have to use it. If I click submit it submits the form. No logs are being created. I have tried uploading the files twice now with no change. Where should I look to make it stop the submit if captcha hasn't been used?
