Error: Headers already sent

 * Hi, when I add your extension I get some "Headers already sent" errors on my wiki. I'm shure I installed the stuff properly. --JazzmanDE 14:14, 17 September 2008 (UTC)


 * Solution:
 * You must put the code into  tags (no more spaces neither blank lines before/after the block). If do not, you get this message because php thinks that is html not php code. See installation section for more detail.
 * Thanks! --JazzmanDE 14:53, 22 September 2008 (UTC)


 * Hi, I'm getting this Error:
 * Warning: Cannot modify header information - headers already sent by (output started at ::C:\xampp\htdocs\MinjusWiki\LocalSettings.php:1) in C:\xampp\htdocs\MinjusWiki\includes\WebResponse.php on line 10


 * Warning: Cannot modify header information - headers already sent by (output started at ::C:\xampp\htdocs\MinjusWiki\LocalSettings.php:1) in C:\xampp\htdocs\MinjusWiki\includes\WebResponse.php on line 10 --JimHawk 10:24, 18 November 2008 (UTC)


 * Trace:
 * Did you put require_once("$IP/extensions/rabcg/rabcg.php"); between  tags in your LocalSettings.php? Nearly all LocalSettings.php files are . So you must put it between ". Therefore I've made a provisional one (?>) an I've put the line there after between "". Both methods had the same result ("Warning: Cannot modify header information - headers already sent by..."). Is it possible that the problem depends on the fact that i possess another language version of Mediawiki as english? Thanks in advance. --JimHawk 09:21, 19 November 2008 (UTC)


 * No, It is language independent. ?> tag isn't necessary. I think that the problem is in rabcg.php and/or groups.php. Is important that there isn't any blank line neither spaces before <?php tag. This tag must be the first thing in these files. Is this correct in your files? --Lodopidolo 18:19, 24 November 2008 (UTC)


 * Yes, i have no blank lines or spaces before <?php Tag. It's really the first thing in my files. Must i install something else, unless the ExtensionFunctions.php, rabcp.php and the groups.php files? --JimHawk 07:49, 25 November 2008 (UTC)


 * No, nothing more. If you want, you can send me the files (LocalSettings.php, rabcg.php and groups.php) and I'll see them. Delete all private information. --Lodopidolo 08:29, 25 November 2008 (UTC)


 * Solution:
 * There was blank spaces before <?php Tag.

Error: array_key_exists

 * Hi, followed your installation instructions and get the following error repeated 30 odd times at the top of every wiki page:

Warning: array_key_exists [function.array-key-exists]: The second argument should be either an array or an object in   /var/lib/mediawiki/extensions/rabcg/rabcg.php on line 41

Cheers


 * Trace:
 * How many times have you declared groups array variables? If you declare it in groups.php you must not declare anyone in rabcg.php and viceversa. Can you tell me more?


 * Solution:
 * Solved. --Lodopidolo 09:51, 26 November 2008 (UTC)

Error on login

 * I have the Special:UserLogin page in the whitelist array, but I cannot access it while browsing as anon. Any ideas?  -Tom


 * Trace:
 * Mediawiki is case sensivity. I think the problem is that correct name (of the page) is Special:Userlogin. Please, try this and tell me more. --Lodopidolo 16:52, 24 December 2008 (UTC)
 * Solution:
 * Solved. Perhaps there wasn't any error. --Lodopidolo 22:23, 15 January 2009 (UTC)

Can't edit user groups

 * All the groups I try to add the user to as admin it wont save the custom groups :( everything else works fine why wont it save my user group permissions.


 * Looks like you can edit groups but they are limited to 16 Characters, i have changed the restriction in the database anyone know where it is in the code ? still wont work.


 * Trace:
 * I don't understand you. Please, explain me what is the problem. Groups must be added in your groups.php file. After you must assign that group to a document as a category name. --Lodopidolo 22:33, 15 January 2009 (UTC)


 * Solution:
 * Perhaps there wasn't any problem. Nobody contacts. --Lodopidolo 16:05, 29 January 2009 (UTC)

Anonymous Acces to public doc

 * I would like to enable anonymous users to read all public articles. I tried a little bit with $wgGroupPermissions, but couldn't figure it out. Is ther any somehow not too difficult mod for this?
 * greets --Malte Mertz 15:25, 19 February 2009 (UTC)


 * Trace:
 * You have two options:
 * You can put all public page you want to access by anonymous user as White pages. In this case all white pages are accessed by every body.
 * You can modify your $IP/extensions/rabcg/rabcg.php, where put:
 * by:
 * Try this and tell me if this is correct. --Lodopidolo 17:18, 19 February 2009 (UTC)

Yeah, it works, very cool. Muchas gracias!--Malte Mertz 16:26, 26 February 2009 (UTC)


 * This was very useful tip as the main need is to restrict just some pages :D Thanks a lot! --Teemuo 07:01, 31 July 2009 (UTC)

Can't Assign Right to User
The extension loaded properly, but the wiki won't save any changes when I try to assign the right to a user. Below is my only line in the groups.php file:

$wgGroupPermissions['Private Data']['private'] = true;

Using 1.13.3 --Leoottawa 22:19, 9 March 2009 (UTC)

Update
Looks like the problem is with spaces. I was able to assign the group PrivateData to a user. --Leoottawa 22:25, 9 March 2009 (UTC)

same here
I too have the same problem with group names containing spaces. It doesn't work with spaces, but works without.

Preventing public adding a page to private category

 * Is there a way to prevent anonymous editors adding a page to a private category? -- Anon., 17:05, 22 March 2009 (UTC)


 * I'm no expert on the issue but I think that would require a lot more complex hack to the mediawiki.. Not sure though. --Teemuo 08:43, 31 July 2009 (UTC)

Usergroups loosing members
I have added line to groups.php $wgGroupPermissions['RestrictedGroup']['private'] = true;

And I have also used the change in topic Anonymous Access to public doc.

The group keeps loosing its members at random intervals - when I log in as admin - I see only the group but no members attached to it.

I'm also using the Extension:LDAP_Authentication -plug-in - should that make any difference.

Any idea why the users lose their membership?


 * Trace:
 * Hi, I don't understand you. I am usign Extension:LDAP_Authentication extension too and I haven't any problem with Extension:Restrict_access_by_category_and_group. Please, explain me more. --Lodopidolo 11:46, 14 September 2009 (UTC)

Not working in mediawiki 1.15.1
Here is my groups.php:

<?php $wgGroupPermissions['TestPrivateGroup']['private'] = true;

Here is version info: MediaWiki	1.15.1

PHP	5.2.6 (apache2handler)

MySQL	5.0.6

Here's my problem:

I have added a user to the TestPrivateGroup group via the user rights management 'special page'. I have created a page with at the bottom, yet there are no restrictions on access, everyone can see the page, even not logged in users. Am I doing anything wrong or does this not work in the latest version of MediaWiki. Thanks.
