If you have never seen one before, captchas are parts of a website where you sometimes need to type in a word to prove you're a human. Captchas are a great way to prevent spam activity on your Joomla 2.5 website because most "bots" that attempt to post spam cannot read the letters contained in the captcha image. In this tutorial, we're going to walk you through the steps for setting up ReCaptcha, a popular captcha system, in Joomla 2.5.

To enable ReCaptcha for Joomla 2.5:

  1. Log into your Joomla 2.5 Dashboard
  2. In the top menu, hover over Site and click Global Configuration
  3. Under the Site tab, set Default Captcha to Captcha ReCaptcha, and then click Save.

    ReCaptcha requires a "key" before it will work. If you test the registration form on your site before entering this key, you will get a similar error message:
    ReCaptcha plugin needs a public key to be set in its parameters. Please contact a site administrator.

  4. To obtain a Recaptcha key, you need to have a Google account. If you don't already have one, sign up for a Google account and then visit https://www.google.com/recaptcha/admin/create (be sure that you're logged into Google). Enter your domain name and then click Create Key. You will then be given both a Public Key and a Private Key, which will look similar to: 6LfnOM47AAAAAB7SSA7fbjH7e1q95htZb34pA1T9
  5. Now that we have our ReCaptcha keys, we'll need to configure Joomla 2.5 with them. In your Joomla 2.5 Dashboard, hover over Extensions (in the top menu) and then click Plug-in Manager
  6. Use the Filter feature to search for captcha, and then click on the Captcha - ReCaptcha link:
  7. Enter your Public and Private Key, and then click Save
  8. Congratulations, you have now enabled ReCaptcha for Joomla 2.5! When you access your user registration page, you will now see a captcha similar to the following screenshot:

Could you clarify what you are referring to? Are you referring to your API key or entering in the captcha itself?

Hello Thavorn,

Sorry to hear you're having problem with the Recaptcha. Make sure that you cleared your browser cache before you test it. It would also help if you could please provide the URL for your site. The information that you have provided is not sufficient for us to troubleshoot the problem.

Please provide us more info and we'll look into the issue further.

Hello Thavorn,

I created a fresh install of Joomla 2.5 and followed the instructions. When I got to step 8 the captcha was visible on my screen. Be sure to check your keys and ensure they are in the right place (private in private and public in public). Other than that, it should work fine.

Kindest Regards,
Scott M

Hello Steve,

Sorry you're having problems with Recaptcha. However, we would need more information in order to determine what's happening. What URL did you use? Did you go check your URL at the site they asked?

Also, the article above is for ReCaptcha not Keycaptcha - that's a totally different product. Are you sure you installed Recaptcha?

Hello Giovanna,

Sorry to hear that you're having problems with the ReCaptcha in Joomla. Unfortunately, you have provided very little information on the overall problem. Can your provide more information on your version of Joomla? It would help to know if you're using add-on for the section as well.

You may also want to review the information found here: Fixing a Broken Captcha in Joomla 2.5 and 3. It might provide a solution for you.

I hope this helps to answer your question, please let us know if you require any further assistance.

Arnel C.
