Solution 2: Verify Google ReCaptcha Key Versions

This error may also arise if the Google ReCaptcha keys are incompatible with the ones you have specified on your CDN admin panel. If you have specified a V2 ReCaptcha version on your Google ReCaptcha admin page and a V3 key on the CDN admin panel it will most likely give you the key type error. So in order to avoid this error, you must verify beforehand that both key versions are identical to each other.

Solution 3: Validate Domain Name

It is necessary that you must verify if your website exists on the identical domain name as registered for ReCaptcha and is added in the domain section of the Google ReCaptcha page. Or in the other case if a mismatch of domains occurs or your website is currently placed on the testing server you will definitely struggle with this error message.

You can verify this by selecting “Plugins” first and then clicking on the “Settings” under the WP-ReCaptcha option. Here you need to enter both the site and secret keys and finally click on save ReCaptcha changes. Once the settings get saved then check to see whether the error for site owner: invalid key type ReCaptcha localhost problem gets eliminated now.

Solution 4: Edit the Database

If the settings are configured as such that the admins of the website also have to enable the captcha option to login into the website and now they are facing the same error message then you need to make certain changes in the database. You just need to disable this option but prior to that make sure that you have already made up a backup. Run the following command in the database to disable the captcha globally:

UPDATE tblconfiguration SET value = '' where setting = 'CaptchaSetting';

Solution 5: New Key Registration [WordPress]

It is quite probable that your ReCaptcha key isn’t valid anymore so you will need to register a new key. Follow these steps to do so:

  1. Register a new ReCaptcha key from here.
  2. To create a new key press the “Plus (+)” icon.
  3. Now fill in the complete specifications including the Label, Recaptcha type, Domain, and Owner.
