I have a namespaced page, the Community Portal, that is not yet populated on our wiki, and is linked from Sidebar. (format Wikiname:Community_Portal When I try to access this and similar pages whose names are within namespaces but don't yet exist, I receive different errors depending on the browser: Chrome: "Duplicate headers received from server The response from the server contained duplicate headers. This problem is generally the result of a misconfigured website or proxy. Only the website or proxy administrator can fix this issue. Error 346 (net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_LENGTH): Multiple distinct Content-Length headers received. This is disallowed to protect against HTTP response splitting attacks." Firefox: "Content Encoding Error The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression. Please contact the website owners to inform them of this problem." IE: "Internet Explorer cannot display the webpage"
Sounds like an issue with your hosting provider.
Can you dump all contents the server sends for that page?
Liangent, what is the best way to do this? Note this results after upgrade from 1.16 to 1.18

Unfortunately it's not public, this is the affected page, but login screen will result, and not error above: http://www.fincawiki.org/en/index.php?title=FINCA_Marketing_Wiki:Community_portal

" Login required You must log in to view other pages. "
How have you configured these additional namespaces? I added the following on my 1.18 install: $wgExtraNamespaces[500] = "Foo"; $wgExtraNamespaces[501] = "Foo_talk"; And then visited Foo:Page and got back only There is currently no text in this page. .... Extra headers sounds like a problem with an extension. What extensions do you have installed?

Could you paste or upload a snippet of your LocalSettings.php file that contains the require() bits and any configuration you've done for these extensions? I tried to reproduce *some* of your set and got no errors. Here's a snip from the LocalSettings.php file I had: $wgExtraNamespaces[500] = "Foo"; $wgExtraNamespaces[501] = "Foo_talk"; require_once( "extensions/Validator/Validator.php" ); include_once( "extensions/SemanticMediaWiki/SemanticMediaWiki.php" ); enableSemantics("localhost"); /* CategoryTree */ $wgUseAjax = true; require_once("{$IP}/extensions/CategoryTree/CategoryTree.php"); /* Collection (Version 1.5) */ require_once("$IP/extensions/Collection/Collection.php"); $wgGroupPermissions['user']['collectionsaveasuserpage'] = true; $wgGroupPermissions['user']['collectionsaveascommunitypage'] = true; /* Renameuser */ require_once("$IP/extensions/Renameuser/Renameuser.php"); /* Cite */ require_once("$IP/extensions/Cite/Cite.php"); /* Embed Document (Version 0.13) */ /* Google doc viewer (Version 0.2.1) */ /* MediawikiPlayer (Version 0.3.0) */ require_once("$IP/extensions/MediawikiPlayer/MediawikiPlayer.php"); /* Nimbus */ /* ParserFunctions (Version 1.4.0) */ require_once("$IP/extensions/ParserFunctions/ParserFunctions.php"); /* RSS Reader (Version 0.2.5) */ require_once("$IP/extensions/RSS/RSS.php"); /* Gadgets */ require_once("$IP/extensions/Gadgets/Gadgets.php"); /* WikiEditor (Version 0.3.0) */ require_once("$IP/extensions/WikiEditor/WikiEditor.php");
First of all, I set "$wgDisableOutputCompression = true;" to disable the compression, and get the exact same message across all browsers: "Page not found The page you are looking for might have been removed, had its name changed, or is temporarily unavailable. Please try the following: If you typed the page address in the Address bar, make sure that it is spelled correctly. - Click the Back button in your browser to try another link. - Use a search engine like Google to look for information on the Internet.

Hello, might this have something to do with old libxml2 version on the server?
I've replicated this issue, by installing a new version from scratch on another domain (using SimpleScripts installer via domain control panel). This one is not password-protected, so you can see what's happening: http://www.d2development.org/wiki/index.php?title=My_WIki:Community_portal http://www.d2development.org/wiki/index.php?title=My_WIki:Current_events
Sorry, your Setup is quite strange: http://www.d2development.org/wiki/index.php?title=My_WIki:Community_portal http://www.d2development.org/wiki/My_WIki:Community_portal It seems as you have redirected /wiki/ to /wiki/index.php in some way (different to the way suggested in [[mw:Short urls]] PS: you've posted your db passwords.
I would like to revive this thread as I am having a very similar, if not the same, issue. Namespaces that have not been populated yet will throw errors when i try to access them. Chrome sometimes gives me the duplicate header error or "Error 330 (net::ERR_CONTENT_DECODING_FAILED): Unknown error". Firefox will sometimes give me a corrupt content error or "The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression". I have recreated the problem on a test wiki simply by installing a fresh version (nothing special done to recreate the issue) at http://www.nesmicroscopy.org/test/index.php?title=Main_Page . Clicking on any of the unpopulated namespaces will throw the error. For example, the Help link http://www.nesmicroscopy.org/test/index.php?title=Help:Contents . Below are some parts of LocalSettings.php . Any help would be greatly appreciated. Apologies if something changes. My webhost is attempting to fix things, but only appears to be making things worse. ## Uncomment this to disable output compression # $wgDisableOutputCompression = true; $wgSitename = "My WIki"; $wgMetaNamespace = "My_WIki"; ## The URL base path to the directory containing the wiki; ## defaults for all runtime URL paths are based off of this. ## For more information on customizing the URLs please see: ## http://www.mediawiki.org/wiki/Manual:Short_URL $wgScriptPath = "/test"; $wgScriptExtension = ".php"; ## The protocol and server name to use in fully-qualified URLs $wgServer = "http://www.nesmicroscopy.org"; ## The relative URL path to the skins directory $wgStylePath = "$wgScriptPath/skins"; ## The relative URL path to the logo.

P.S. It seems like a common link between our problems might be that we both use iPage as our webhost. Just a thought. Also, I want to mention that I cannot run any scripts (including installing extensions) because our iPage doesn't allow it.
I've been looking around for a solution to this as well. As it turns out, I'm also using iPage as my host. I recently moved from free hosting to iPage and that's when this started showing up. I think it may actually be a problem with their hosting. I think we need to put in a few tech calls to iPage and see if they can figure out what the problem is. I found a workaround for the problem that works with iPage. If you search for the page that you're trying to add/create/"edit" in a non-main-namespace and then use the auto-generated "Create the page "Example:Page" on this wiki!" to edit that page, it'll allow you to. Once there's content in the page, you can access it through the tab as normal.
I made many many tech calls to ipage. They were less than helpful in solving the problem. I found a way to make it work. Basically, you cannot use .htaccess to password protect your page. You will have to use wikimedia methods to secure your page instead. I also had to add a .htaccess file to the wiki directory with the following code: DirectoryIndex index.html index.php ErrorDocument 404 /404.php ErrorDocument 403 /404.php If you put any sort of error message in the file, it will show up on Google Chrome. The page will load, but the message will also load over it. This does not happen with Firefox or IE. Since I have set this up, it has been working properly. It is disappointing that we cannot use .htaccess to password protect the page, but wikimedia has a bunch of way to protect the wiki page and prevent any random person from creating an account. I hope this help. Please let me know if I need to be more clear on any topic.
i believe more in the iPage hosting as the cause of the issue, since I just moved to a new iPage site and they offer mediawiki yet whether I reset the frame option to FALSE it still keeps the err. err I get is Duplicate headers received from server
(In reply to comment #18) > DirectoryIndex index.html index.php > ErrorDocument 404 /404.php > ErrorDocument 403 /404.php Added this in a .htaccess in the wiki dir and OMG it works ! tnx.
