Extension talk:ReCAPTCHA

deleted the following
I deleted the following two points from the Notes section of the page since they appear to be quite unnecessary.


 * 1) You will need to call ConfirmEdit in LocalSettings.php using require_once( "$IP/extensions/recaptcha/ConfirmEdit.php" ); (in addition to require_once( "$IP/extensions/recaptcha/ReCaptcha.php" );).
 * 2) I found the previous instruction to be false. I initially enabled ConfirmEdit, but it caused a problem with the redeclaration of a variable, so I disabled it and reCAPTCHA then worked fine, using MediaWiki 1.11.0 on Linux.

The first is not right - recaptcha.php does a require_once( "ConfirmEdit.php" ); so you clearly don't require the LocalSettings.php change. This of course makes the next statement redundant. Michael Daly 02:31, 12 October 2007 (UTC)


 * This extension only worked for me by disabling ConfirmEdit (even after checking to make sure I had the most up-to-date version). T0lk 08:12, 28 November 2009 (UTC)

reCAPTCHA API Key Not For Current Domain Error
I just upgraded to MediaWiki 1.11 and everything seems to be working fine but when I encounter a page that usually have a reCAPTCHA on it, it now says that the reCAPTCHA key wasn't created for the current domain, but I had been using the same API key before I upgraded and everything worked fine, anyone have any idea what can be causing this?

Fixed: Nevermind, for some reason I did indeed have to create new keys, even though before upgrading the ones I had worked fine. --BlaenkDenum 01:10, 20 November 2007 (UTC)

ConfirmEdit Works. With reCAPTCHA enabled shen saving changes on any account the following error results:

Fatal error: Cannot redeclare class SimpleCaptcha in bla/bla/bla/extensions/ConfirmEdit/ConfirmEdit_body.php on line 66

sup wit dat?


 * You're not supposed to require_once both ReCAPTCHA and ConfirmEdit in LocalSettings.php. —Emufarmers(T 06:08, 12 June 2009 (UTC)

I have the same fatal error. But there is no captcha on the site when I take out require_once( "$IP/extensions/ConfirmEdit/ConfirmEdit.php" ); and leave require_once( "$IP/extensions/recaptcha/ReCaptcha.php" ); It also doesn't work if i leave the first require_once and take out the second. Ideas? I am using the latest versions of mediawiki, confirmedit.php, and recaptcha.


 * Confirming above. No captcha when I remove require_once( "$IP/extensions/ConfirmEdit/ConfirmEdit.php" );, and fatal error when included with require_once( "$IP/extensions/recaptcha/ReCaptcha.php" );.  MediaWiki 1.15.1, ConfirmEdit r50221 --FoohonPie 22:33, 9 August 2009 (UTC)
 * So it turns out I was wrong, I just wasn't testing properly. Works fine if you remove the ConfirmEdit require, just make sure when you test that you are including an external link(with  tag and all), otherwise the captcha won't be triggered. --FoohonPie 22:37, 9 August 2009 (UTC)

Doesn't work any more?
It appears this plugin doesn't work on editing pages any more. Confirm? --Jlp09550 05:53, 4 June 2010 (UTC)


 * 1) I have the same problem: When trying to edit/save a page I get errors, so nothing is saved. (Registering with a new account works however) ~ eyerouge 28 june 2010
 * 2) Update: Problem is now solved - in my case it was caused by me downloading the extension from the re-captcha site (http://recaptcha.net/plugins/mediawiki/). The file "ConfirmEdit.php" in that extension package is probably very outdated as the re-captcha extension package is dated back to may 2007. To get it all to work I simply a) downloaded the re-captcha extension b) installed it according to it's own instructions c) then downloaded the latest ConfirmEdit package d) extracted ConfirmEdit.php from that and e) replaced the old ConfirmEdit.php in the re-captcha package with the ConfirmEdit.php in the fresh ConfirmEdit-package. Did the trick for me. ~ eyerouge 28 june 2010

Unable to prove humanity using reCAPTCHA plugin
Using MediaWiki 1.15 and the latest version of the reCAPTCHA wiki plugin (as downloaded from the official site this morning), the reCAPTCHA appears as expected on the account creation page. However, when clicking the "create account" button to submit information, the page returns a red box with the message "Login error Incorrect or missing confirmation code." (tried 4 times over 2 hrs) Inside the ReCAPTCHA box, the message "incorrect. try again" also appears- disabling the plugin allows account creation to proceed normally. This problem appears unique to the use of the wiki plugin, and I am still able to solve reCAPTCHAs on other sites without trouble. Any suggestions would be much appreciated. --141.211.122.223 18:27, 22 June 2010 (UTC)

Being bypassed?
I've been having a problem with spambots being created (who luckily can't edit), but they somehow kept creating an account every 30 minutes AFTER I installed this program. How the hell are they bypassing this? I tested it for myself and the captcha seems to work.
 * No offense, but this program isn't very effective, spam bots get in everyday even though I'm using this program. How about making it better? --Bluesoju 11:29, 8 November 2010 (UTC)
 * Same here. It has worked very good in the past, but since half a year it's quite useless for me. There are many spambots registering. --87.176.123.41 22:50, 16 November 2010 (UTC)

Missing from SVN server
this extension seems to be missing from the SVN server where it's implied above it once was. The download link on this extensions page is to super old google code from ca. 2007. anyone know where i can get this extension?
 * This extension was never in SVN. The page for the extension at recaptcha.net was redirected to a page on Google Code at some point, but the actual download source has not changed. —Emufarmers(T 09:22, 4 December 2010 (UTC)

BUG: Permissions Issues on UNIX-Based Systems
I noticed a bug with this and it took me a while to find it. I originally got a 500 error which denotes a problem in the code, which traced back to a permissions issue. In the logs of the webserver software I use (Apache), I found this:

[Mon Dec 27 17:25:43 2010] [error] [client ::1] PHP Warning: require_once(/var/www/smbx-wiki-test/extensions/recaptcha/ReCaptcha.php): failed to open stream: Permission denied in /var/www/smbx-wiki-test/LocalSettings.php on line 135

I'm not sure if any of you have gotten this, but when I looked into the folder itself, I found that the permissions for the recaptcha folder were defaulted to owner use only (in my case, root, which owns the /var/www folder). To rectify this, the following command should be done from the extensions folder in a terminal (as superuser, just to be certain):

chmod --recursive +rw recaptcha

Not sure if this helps anyone, but I thought I'd let this information be out there. --TrekCaptainUSA 22:39, 27 December 2010 (UTC)


 * This isn't a bug, and it's unrelated to the extension: you have a restrictive umask set. —Emufarmers(T 23:00, 27 December 2010 (UTC)
