Thank you.
It seems your forms get submitted before we get a response from google with keys.
I need some time to fix this issue.
If you are in a hurry and want a refund let me know.

I can check when it is active. Do you have any staging site for this website? Or can you make a test site with this same settings for testing?

May be someone from that message has blocked you.
You can add your username in the whitelist in Front End PM PRO > Settings > Security, That may bypass that check.
Let me know.

You can go to Front End PM PRO > Settings > Security and check “Who can send new message” to only Administrator

1. May you please let me know which version of the plugin you are using?
2. Can you please let me know last 6 digits of your license key?
