PROBLEM:
Quick Contact has stopped working on several websites that I support, including:
http://www.astronomysyndicate.com/
https://www.returnofthemessiah.com/
https://www.qedoshim.com/
http://www.c3q.org
and others.

ERROR MESSAGE:
I either receive a "Session check failed!" or "CAPTCHA_SPAMER" (no language lookup available?) error message.

TROUBLESHOOTING ATTEMPTED:
- I've tried submitting a contact request via multiple browsers, including Internet Explorer, Edge, Chrome, and Firefox.
- I've uninstalled and reinstalled JA Quick Contact v 2.6.5.
- I've uninstalled and reinstalled JA Multi Captcha Engine v 2.5.6.
- I've ensured no other captcha plugin was enabled.
- I've verified the ReCaptcha site key and secret key are correct.
- I've deleted any template overrides for the mod_jaquickcontact (and then restored them once it turned out those were not an issue).
- I've deleted the cache (both server side and client side) to ensure no old content or scripts were present.

I have discovered that the captcha plugin appears to be pointing to the wrong Google address for the ReCaptcha scripts. Checking the FireFox Developer Tools "Network" tab, there are two 404 errors this address: https://www.google.com/recaptcha/api/js/recaptcha_ajax.js during page load.

I need assistance to resolve this issue.

Thank you!
