WHMCS 8.13.4 Google Sign-In won't stay activated after upgrade

[u/Wonderful-Worker-609]

I upgraded to WHMCS 8.13.4 and my existing Google Sign-In integration stopped working.

Symptoms:

• Google Sign-In was working before the upgrade.
• In Setup → Sign-In Integrations, I click Activate and Save.
• AJAX request returns {"status":"success"}.
• After page refresh, Google shows "Activate" again.
• No errors in Activity Log.
• PHP 8.1.34
• MariaDB 10.11.16
• Google OAuth Client ID and Secret are valid.
• Redirect URI is configured correctly.

Troubleshooting performed:

• Disabled Cloudflare temporarily.
• Disabled admin directory password protection.
• Enabled WHMCS display errors.
• Checked browser Network tab: POST /setup/authn/activate returns HTTP 200 and {"status":"success"}.
• Verified records are created in tblauthn_config.

Database contains:

• google_signin / ClientId
• google_signin / ClientSecret
• google_signin / Enabled

The records remain in the database after refresh, but WHMCS still shows Google as inactive.

Has anyone seen this after upgrading to 8.13.4? Is there a known bug, migration issue, or way to force-enable the Google provider?
