Hi.

New user accounts attempting to register on the site are returning the following errors:

Notice: Constant RECAPTCHA_API_SERVER already defined in /var/www/osl/administrator/components/com_k2/lib/recaptchalib.php on line 49

Notice: Constant RECAPTCHA_API_SECURE_SERVER already defined in /var/www/osl/administrator/components/com_k2/lib/recaptchalib.php on line 50

Fatal error: Cannot redeclare class ReCaptchaResponse in /var/www/osl/administrator/components/com_k2/lib/recaptchalib.php on line 148


Here are lines 49, 50, 51, & 148 on the php file:


47 * The reCAPTCHA server URL's
48 */
49 define("RECAPTCHA_API_SERVER", "www.google.com/recaptcha/api");
50 define("RECAPTCHA_API_SECURE_SERVER", "www.google.com/recaptcha/api");
51 define("RECAPTCHA_VERIFY_SERVER", "www.google.com");


148 class ReCaptchaResponse {
149 var $is_valid;
150 var $error;
151 }


Any assistance would be greatly appreciated.

Hi. It looks like an other extension is using the same library with K2. Try to look for third-party extensions that provide reCAPTCHA in your site.

I'm using J 3.3.0 | Jomsocial 3.2.0.5 | JFBConnect 6.0.5 | SCLogin 4.0.5

Thanks for the responses guys but I looked all over and couldn't find another extension which uses reCaptcha. It's weird because this was working fine not too long ago. :/

I've disabled several plugins and tested after clearing server and browser caches. I've done the following:

Implemented solutions per thread - getk2.org/community/English-K2-Community/10508-SOLVED-Re-reCaptcha-not-working
Disabled - JCH Optimize Pro plugin
Disabled - NoNumber CDN for Joomla plugin
Disabled - Captcha reCaptcha plugin
Disabled - K2 Social Profiles plugin
Disabled - System Cache

After doing the above it still returns the same errors. Could the ordering of the plugins be causing this issue?

I am at a loss. :(

Just disregard this thread. It appears that the Jomsocial reCaptcha takes precedence in the new account registration and K2 anti-spam setting (in Advanced Tab) was on for registration as well. I just disabled the K2 reCaptcha setting for registration and it works again.

Conflict solved as no members will be registering directly through K2 extension on front end anyways.
