Recaptcha ERROR: Invalid domain for site key
To de-escalate the "Invalid domain for site key" fiasco, it boils down to a mismatch between the active reCAPTCHA site key and registered domain. The resolution recipe goes as follows:
- Embark to the mystical land of Google's reCAPTCHA admin console.
- Unearth the aged site key sowing trouble.
- Seed your domain in the fertile "Domains" pot.
Make sure yourdomain.com is immortalized in the list of domains:
Hit that Save button and hang tight as the digital gears are in motion, spreading updates through the wires.
Audit your Subdomains: No Stone Left Unturned
The game changes with subdomains (sub.yourdomain.com) as they unfold a little different tale. Keep an eye out for these caveats:
- Explicitly list subdomains: Clear communication is key, jot each progeny (subdomain) in your reCAPTCHA setup.
- Wildcards are Wild: Wrestling many subdomains? Use a wildcard (e.g.,
*.yourdomain.com) to tame them. - Contextual validation: Validate the reCAPTCHA code's fitment in each subdomain. Bet the Hulk didn't see that coming!
Occasionally, you might meet the persistent error beast even after following the rules. Here's a concoction to combat:
- Domain Validation Summon: Attention, only to be used when regular potions are ineffective. Disable this option but remember, it exposes the Achilles heel - security loopholes.
- Cookie-monster and Cache-craze: Feast on the cookies and cache to avoid reCAPTCHA conflicts.
- Server and Hosting Soul-switch: Moved the soul (server or hosting) recently? Ensure it didn't disturb reCAPTCHA's spiritual balance.
Remember, one site key appeases multiple domains and subdomains. It's like Gollum’s ring, one key to rule them all!
The Extra Mile: Pro tips for reCAPTCHA Setup
Veterans know, marching the extra mile helps win the war. Tactics for an error-free reCAPTCHA setup:
- Waiting Game: Changes need time to blend. After modifications, stay put a few minutes. Frustrating? Sure, but Rome wasn't built in a day!
- Development Shenanigans: During battle rehearsals (development), disable domain validation for easy debugging. A cautionary note: remember to summon it back during the real deal (production)!
- Security Siren: Though disabling domain validation assists debugging, beware it's akin to stringing bells around your neck in a lion's den.
