Fix 1: Downgrade to ReCaptcha V2 Key

Most popular web frameworks currently do not support V3 keys, so the first method for you to fix the “error for site owner: invalid key type” issue is to downgrade to the Recaptcha V2 key. Now, let’s see how to do that:

Step 2: Select Contact Form 7 and Integrations, then, remove the API keys.

Step 3: Next, click Plugins to select the Add Plugin option.

Step 4: Find Invisible ReCaptcha For WordPress, and then install and activate it.

Step 5: Now, go to the ReCaptcha Admin account, choose ReCaptcha v2 (Invisible) and generate new keys. Then, you will receive the site key and secret key when you finish the form.

Step 6: Copy the site key to the clipboard, open WordPress again, and go to Admin -> Settings -> Invisible ReCaptcha.

Step 7: In the Site Key field, paste the site key you copied earlier, and then go back again to copy the Secret Key. Then paste the secret key into the secret key field.

Step 8: Select the Save option, then go to the Contact Form tab, then check the Enable Protection for Contact Form 7 option here, and then click the Save Changes option.

Fix 2: Verify Domain Name

You should make sure that your website exists and is the same as the domain name registered for ReCaptcha, and whether it has been added to the domain name section of the Google ReCaptcha page.

You can verify by first selecting Plugins and then clicking Settings under WP-ReCaptcha options. Here, you need to enter the site key and secret key, and finally click Save ReCaptcha changes.

Fix 3: Edit the Database

If the configuration is set so that the site administrator must also enable the verification code option to log in to the site, and now they encounter the same error message, then you need to make some changes in the database.

You only need to disable this option, but before doing so, make sure you have composed a backup. Run the following command in the database to globally disable the verification code: Update tblconfiguration SET value =” where setting =’CaptchaSetting’; 

Then, check if the “error for site owner: invalid domain for site key” issue has gone.
