Hi @odisant,
thanks for the reply! I am not using any thirdparty plugin for recaptcha. I am using the build in integration of contact form 7 (Version 5.2)
BTW: I am using recaptch v3.
I generated yesterday as well a new API Key and integrated that one. Now it started to work sometimes.
When I fill in the form for the first time, I get an soam error but when I than just press the submit button again it sends the message.
Any ideas?
