Repair Missing reCaptcha

My site’s Google reCaptcha suddenly vanished. Until then it worked flawlessly, so the keys and basic integration are already in place—the widget (v2) just no longer renders on the page.

I need you to trace whatever dependency, script conflict, or mis-configuration is blocking it and get the badge back on display. A clean, minimal fix is preferred: update the current snippet or plugin settings rather than bolting on an extra library that will slow the site down.

Deliverable: reCaptcha visibly loading and functional on signup page where it previously appeared, with a quick note of what was changed so I can track it in version control.
