Just upgraded from 7.6.0 to 18.104.22.168: https://wordsmith.org/board/
Followed the procedure in the upgrade docs. Upgrade completed without any errors.
In Control Panel, I don't see any new features such as: Support for Google reCAPTCHA. In fact, the registration screen now shows a broken image in place of a captcha image that used to work earlier (paths to Convert and Mogrify work, as earlier).
What am I doing wrong?
