Why did reCaptcha disappear in JOOMLA 3?

Question

Joomla

Hello.
Site on JOOMLA 3. Captcha suddenly disappeared. Was and was not. I edited the number in the header, then edited the css of the feedback form. Cleared cookies, cache, everything. There was a captcha. I'll be in in half an hour. All! No captcha. I did all the advice given on the Joomla forum. All according to the instructions. Still doesn't work. Debugger error
JQMIGRATE: Migrate is installed, version 1.4.1
