How to Fix reCAPTCHA Not Working in WordPress (2023)
Is the reCAPTCHA not working on your WordPress website? If yes, you can get the answer on fixing it here!
Google offers reCAPTCHA, a CAPTCHA-like system, to help you protect your website from spam or abuse. It is like a shield to your website that protects you against “bots” and other malicious software.
If you're facing a situation where reCAPTCHA is not working as expected, you're not alone.
In this article, we’ll show you how to fix reCAPTCHA not working in WordPress. By the end of this article, you’ll know the possible reasons for reCAPTCHA not working and how to fix them.
reCAPTCHA Not Working (TOC):
What is reCAPTCHA?
Google reCAPTCHA is a CAPTCHA-like system that was introduced by Google in 2009. It offers all that is required to strengthen your site security.
There are 3 types you can use for your WordPress login page, including:
1. Score-based (v3):
The higher the score, the more likely the user is human. A webmaster has to decide (and program) whether to block, challenge, or do nothing when a user's score drops below a certain threshold.
Google reCAPTCHA V3 works in the background. It consists of 11 levels for scores with values that range from 0.0 to 1.0. This reCAPTCHA type understands a user's behavior based on the score (measured based on the interaction on the login page).
If the score is higher, reCAPTCHA takes that as a more human-like response.
For example, if the score is 1.0, it means that a human is there on the login page. But if it is 0.0, it simply indicates some bot is trying to log in.
2. Challenge (V2) "I'm not a robot" tickbox:
Google reCAPTCHA V2"I'm not a robot" checkbox is a widely used security measure on websites to distinguish between human users and automated bots.
It was developed by Google and is designed to protect websites from spam, abuse, and other malicious activities.
This is what reCAPTCHA (V2)"I'm not a robot" looks like:
See, this is how it appears on the login form:
3. Challenge (V2) Invisible reCAPTCHA badge
There's also a Challenge (V2), "Invisible reCAPTCHA."
It also doesn't require users to interact with a checkbox or challenge. Instead, it works in the background and analyzes user behavior to find out if they're likely human or not.
Why is reCAPTCHA Not Working in WordPress?
There could be several reasons your reCAPTCHA failed to work properly in WordPress; some common ones are:
- The Incorrect Site: The site and secret keys are unique to each website, and if they are incorrect or not entered correctly, reCAPTCHA won't work. Double-check that you have entered your website's correct site and secret keys.
- More Than One reCATCHA Activated: If you have more than one reCAPTCHA type activated on your Login/Register/ Forget pages, i.e., V2 and V3, it might end up causing a reCAPTCHA issue.
- Error for Site Owner: Invalid Domain for Site Key.
- Plugin Conflicts: If multiple WordPress plugins are installed that use reCAPTCHA, they may have conflicts. Try deactivating other plugins and see if that solves the issue.
How to Fix reCAPTCHA Not Working in WordPress?
If you're encountering issues, there are several steps you can take to diagnose and fix the problem.
1. Invalid Site Key
Invalid site keys used in integrating your WordPress with Google reCAPTCHA tend to prompt reCAPTCHA, which isn’t working in WordPress.
The error message suggests “ERROR for site owner: Invalid site key.” This probably happens if Site and Secret keys, copied from the Google reCAPTCHA, were incorrectly pasted to your plugin settings or accidentally deleted from your Google reCAPTCHA account.
See how it appears:
How to Fix it?
You can fix this problem by ensuring the right key in the settings of your reCAPTCHA plugin.
Simply double-check the keys you have from Google reCAPTCHA and match the keys you’ve applied to your LoginPress reCAPTCHA Site and Secret key fields.
2. Error for site owner: invalid domain for site key
When you see this, it means the domain or site URL added to the v3 Admin Console needs to be corrected.
How to Fix It?
To fix this, log into the console, look for the Domains setting, and edit your domain/ site URL. After that, return to your WordPress form and refresh the page.
3. Plugin Conflicts
reCAPTCHA is often used in WordPress through third-party plugins that integrate it into the website. These plugins can sometimes conflict, causing it to stop working.
How to Fix It?
To resolve plugin conflicts, you should first try deactivating other plugins that share the same functionality and see if that solves the issue. If it starts working after deactivating a plugin, you can try activating the other plugins one at a time to see which one is causing the conflict.
4. Recaptcha validation failed
Sometimes, you might encounter a reCAPTCHA validation failed error. It happens because you might have enabled both v2 and v3 types simultaneously.
How to Fix It?
To fix this, you’re required to have either V2 OR V3 type activated on your site.
Select the one you want, and delete the other.
When done, the issue will automatically be resolved.
