It is not possible to set up Captcha

It sounds like you're experiencing an issue with popup windows in PHPRunner. Here are some steps you can take to troubleshoot the problem:

1. Check Browser Settings: Ensure that your web browser allows popups. Sometimes, browsers block popups by default, which can prevent them from opening in PHPRunner.

   
   

2. JavaScript Errors: Open the browser's developer console (usually F12 or right-click and select "Inspect") and check for any JavaScript errors that might be preventing the popup from opening.

   
   

3. Update PHPRunner: Ensure that you are using the latest version of PHPRunner. If not, consider updating to the latest version, as newer builds often include bug fixes and enhancements.

   
   

4. Review Popup Settings: Double-check the settings in PHPRunner for the popup window. Make sure that it's configured correctly and that the conditions for it to open are met.

   
   

5. Test in Different Browsers: Sometimes, the issue might be specific to a particular browser. Try accessing your application in different browsers (Chrome, Firefox, Edge, etc.) to see if the problem persists.

   
   

6. Disable Browser Extensions: Some browser extensions can interfere with the functionality of web applications. Try disabling any extensions you have installed and see if that resolves the issue.

   
   

7. Check Server Configuration: If your application is hosted on a server, ensure that there are no server-side restrictions or configurations that might prevent popups from functioning correctly.

   
   

8. Consult PHPRunner Forums: Since you mentioned that others might have the same problem, check the PHPRunner forums or community discussions for similar issues. You might find solutions or workarounds shared by other users.

   
   

If you've tried all of the above and the issue still persists, consider reaching out to PHPRunner support for further assistance. They might be able to provide more specific guidance based on the version and configuration you are using.

This part:
(Optional) Find a legacy reCAPTCHA secret key

If you want to integrate with a third-party application that does not use the reCAPTCHA Enterprise API, you need the legacy secret key.

For every site key that you create, reCAPTCHA creates a legacy reCAPTCHA secret key (legacy secret key), which you can use with your third-party application.

If you need the secret key for a reCAPTCHA Classic key, then migrate the key to reCAPTCHA on Google Cloud and find the legacy secret key.
