I have inserted the reCaptcha public and private keys in the advanced tab and captcha still does not appear. I have checked and rechecked my settings.

It appears I'm not the only one with this problem... can someone please answer this post.

Hi I encountered a similar problem and found the solution as follows:

The new version of Joomla - 2.5 has a captcha form element built in - which is great. However, if you install K2 (2.5.6) this also uses the same ReCaptcha element. Unless you get the settings just right the two will conflict in strange ways. In order for the system to work you need to follow these three steps:

1. Disable the Captcha -ReCaptcha component in the Joomla Component Manager
2. Go to the User Manager and then to the Options (Users Configuration) and set Captcha to be "none selected"
3. Go to the K2 configuration and enable Captcha and enter your public and private keys.

If you don't follow all three steps, then both captcha's will be used but only one will be displayed (the K2 one I think) and you will get error messages similar to this:

"The words you typed did not match the ones displayed. Please try again."

Or if you disable just the K2 Captcha then you get this error message:

Empty solution not allowed.

Hi,

I've got the same problem and followed your instruction but still the re-captcha is not showing.
You say: Disable the Captcha -ReCaptcha component in the Joomla Component Manager.
But in the component manager I don't see something with the re-captcha....so I think you ment the plugin manager.
However......re-chaptcha is still not working.

Any other solutions or suggestions?

Regards, The

Theo, did you get this figured out?

I disabled the captacha plugin.
Enabled and Pasted in the recaptcha keys into the K2 / Parameters / Advanced / Anti-spam Settings

But it is not showing up

I need to launch this site today.

anyone have any suggestions?

Has anyone figure out why the images does not appear? I got the same issue.

As-salamu alaykum,
I have resolved the problem :)
You don't have to disable anything, just to get the Captcha - ReCaptcha plugin working on K2 comment you have to follow these steps:

1 - ON www.google.com/recaptcha Go to
- USE reCAPTCHA ON YOUR SITE
- ADD Gmail account if you don't have, or log in if you have.
- Go MY ACCOUNT -> + Add a New Site
- Create a reCAPTCHA key -> ADD your Domain -> Create a Key.
- Copy (Public Key and then you will copy the Private Key)

2 - On your admin panel go to:
- Component -> K2 -> Parameters -> Comments-> Active reCaptcha -> Yes.
- Go to Component -> K2 -> Parameters -> Advanced -> Anti-spam.
- Past the two Key that you have from Google. (Public and Private Key)
-> Refresh you site and you got it ^_^

IF YOU STILL DON'T HAVE THE CAPTCHA WORKING:
Make sure you have enabled the K2 plugin and Comments on the Category options.
That should be resolving your problem.

- IF, IF that is still not working:
- Go to your site
- Click " F12 " on Google Chrom / Control+F12 (Firebugs, Firefox)
- Refresh your web site
- If you have a JavaScript errors try to find what is your problems and solutions.
- Last thing if you don't have any JS problem, You should re-install joomla xD

That is all
Thank you, your brother from Tunisia :)

I disabled the Captcha - ReCaptcha plugin as suggested, still didn't work. Then I realized I had created the recaptcha keys for a specific domain and I was working on a test site... ooppsiiee.

So I just created global keys and works fine. I even tried to enable the plugin back on and still works :P

Thank you Khalil, I've been trawling forums for days trying to sort my User Registration Captcha! It worked fine in Chrome, but intermittently wouldnt show in IE8, then when installed Joo Captcha instead, it displayed but kept saying "words dont match" . Did as you suggested in your post and all works fine.

@ Steve Scott
Thank you very much !
This is the only that works in k2!

Wow! very good explanation. It works
Thanks - Merci. J'ai gagné du temps.

thanks a lot. it helped! well explained also. :)

I still get the error:

I have installed:

1. Joomla 2.5.8
2. K2 2.6.5
3. LoginRadius to use social media to connect,'

When I login through LoginRadius and one of the social media connectors I get the error:
"The words you typed did not match the ones displayed. Please try again"

I have followed the above instructions.
1. Disabled the Captcha ReCaptcha Extension
2. Disabled the Captcha ReCaptcha Plugin
3. Set User Configuration - Captcha "None selected"
4. Set K2 Parameters for Comments to Enable reCaptcha in Comments to "Yes"
5. Copied and Pasted Keys to K2 Advanced Parameters
6. Enabled reCaptcha on Registration Form
7.Enable StopForumSpam.com integration on the user registration form = Yes

However, I still get the message:
"The words you typed did not match the ones displayed. Please try again"

Any help would be GREAT.

Thanks,

Having a similar issue here.

Joomla 3.0.3
K2 2.6.5

Disabled the system default Captcha - ReCaptcha plugin.
Set K2 to load a local copy of jQuery v1.8.2.
Changed Captcha setting in Users Manager Options to '- None Selected -'.
Updated public and private keys in the K2 -> advanced ->anti-spam settings section and set enable reCaptcha to 'Yes'.

The captcha to solve appears in the comment section as expected.

Entering a comment and leaving the captcha solution empty results in the message 'The words you typed did not match the ones displayed. Please try again.'

Entering any solution (correct or not) and submitting does nothing.

I've confirmed that my public and private keys are for the domain in question. Similarly, I am not getting any scripting in the browser debugger for Chrome or IE10.

Anyone have any suggestions?

So, having discovered a similar issue in form submissions using the system recaptcha plugin, I managed to figure out my own issue.

It seems that recaptcha requests via IPv6 have some sort of issue going on, so any box with a v6 address is likely going to have socket errors trying to verify a captcha response.

The solution to this is to either remove IPv6 from the machine running Joomla, which isn't terribly optimal, or hack any references in the recaptcha libraries to not make requests via IPv6.

This can be done by changing the fsockopen call made in /administrator/components/com_k2/lib/recaptchalib.php on line 91

from
...@fsockopen($host, $port,...
to
...@fsockopen(gethostbyname($host), $port,...

Similarly, the default system recaptcha plugin at /plugins/captcha/recaptcha/recaptcha.php can be changed on line 189.

As gethostbyname() doesn't support IPv6, it gets around the problem.

Probably not the best solution, but until requests made using IPv6 are reliable, this will work until someone goes about adding an actual option to determine what protocol(s) the request will use.

For what it's worth, 3.0.2 and 2.6.5 appear to be just fine with both recaptcha plugins (system / k2) enabled.

Does anyone have a fix for this yet?

I tried your idea Brad, and it still won't work. As it stands now, no one can register on my site because of this.

Odd thing is, it worked last week and the only thing I have done is instal JFBConnect. I was actually testing this out and decided to make a test account when I ran into this issue. Problem was, I could not get 'facebook login' to work, but I did figure out that if I disabled K2 captcha it worked fine. Problem with that is, I would end up with this message:
Empty solution not allowed.

So I followed the steps in the other post. and this is what I end up with:
The words you typed did not match the ones displayed. Please try again.

Is anyone with this problem using JFBConnect?

Same thing here. I haven't been able to make it work: Any way I fill in the captcha it will still tell me it's wrong. The only thing I can think of now is to uninstall K2 :-( because I need users to be able to register. Still, I hope someone finds a solution for this problem.

Hi, uninstalling K2 worked. Incidentally it also solved some of my other issues that I hadn't connected to K2, like my registration form being in English when it should've been in Dutch...

Hello Imke, your registration page was not an issue, if you uploaded the Dutch translation for K2 it would have been in Dutch.

As far for registrations and reCaptcha As-salamu alaykum has posted a very thorough step by step solution.
