TWiki is a flexible, powerful, and easy to use enterprise collaboration platform. It is a Structured Wiki which can be used to run a project development space, a document management system, a knowledge base, or any other groupware tool, on an intranet or on the internet.

Release 4.0 is the first major release in a year, adding simplicity in installation, integrated security features, and much more.

Major New Features

  • WYSIWYG editor (beta)
  • Revamped PatternSkin with a modern look and lots of customization options
  • Much simpler install and configuration
  • Integrated session support
  • Webserver-independent login/logout
  • Security sandbox blocks all possible routes for remote command execution on the server
  • New editing model with conflict resolution allows freer collaboration, without fear of overwriting other people's changes
  • Multilingual UI: Chinese, Danish, Dutch, French, German, Portuguese, Spanish, Italian, Polish, Swedish
  • E-mail confirmations for registration to prevent spamming
  • Hierarchical sub-webs (beta)

TWiki Patch Release 4.0.4

TWiki Release 4.0.4 supersedes TWiki Release 4.0.3, and addresses one security related update and only very few selected important bug fixes.

If you have TWiki Release 4.0.3 installed, you can download and install just the newer files contained in changed files.
This release contains very few changed files and no matter which setting you have changed and tailorings you have made the -changed zip file should be 100% safe to copy on top of your running TWiki 4.0.3 installation.

If you have TWiki Release 4.0.2 installed and still have not upgraded to TWiki Release 4.0.3 you can either install a full new TWiki Release 4.0.4 or first upgrade to TWiki 4.0.3 using the TWiki-4.0.3-changed.zip and then apply the much smaller TWiki-4.0.4-changed.zip on top.

The -changed file is distributed only as a zip file. When you copy a zip file on to a Unix/Linux/BSD environment the new files will have the default file access rights. The topic SettingFileAccessRightsLinuxUnix tells you how to quickly restore access rights on your entire TWiki directory.

ALERT! Please review SecurityAlertSecureFileUploads and secure your webserver so that uploaded files cannot be executed. Securing the file uploads is done in two layers: Webserver configuration (needs to be done manually), and upload filter (included in 4.0.4 release and changes file.)

List of Changed & Removed Files


No files have been removed


sorry to say, but the HTML layout seems to be complete broken for 404 install from scratch. Update from TWiki version Wed, 01 Feb 2006 build 8671 is not possible either.

-- FerdinandGassauer - 05 Jul 2006

You are welcome to ask your question in the support web. I am sure there is nothing wrong with the "HTML layout" in TWiki-4.0.4 and I am sure we can help you solve the problem if you tell us a bit more details. See SupportGuidelines

An often reported problem when upgrading always ends up being style sheets being cached by the browser. See e.g. WebLeftBarPosition. Either clear your cache or force a complete reload from your browser.

-- KennethLavrsen - 05 Jul 2006

Just want to report that installing a fresh TWiki works after clearing the cache.

-- FerdinandGassauer - 06 Jul 2006

for upgrade from 4.0.0 to 4.0.4 I had to copy these files from the new fresh directory to the updated directory:

tar cvf /tmp/cs.tar `find . -name "*css"  # fixes Layout problems
tar cvf /tmp/ss.tar `find . -name "*.js"|grep -v ",v" |sort` # fixes edit problem (no edit box)
tar cvf /tmp/Templ.tar `find .  -name "*Template.txt*"|grep -v ",v" |sort` # not sure if really necessary
tar cvf /tmp/Tip.tar `find . . -name "*Tip*"`# not sure if really necessary
tar cvf /tmp/templ.tar templates # not sure if really necessary
and install these files in the new twiki directory
  • still not working: Tip of the day

-- FerdinandGassauer - 06 Jul 2006

"Tip of the day" was displayed "raw" because one or more plugins have not been enabled.

-- FerdinandGassauer - 06 Jul 2006

It seems to be mandatory to clear the cache manually to convince the browser (firefox) to load the new style sheet. This is not very convenient, because users usually do not know how to do it.

-- FerdinandGassauer - 10 Jul 2006

i think this is a Firefox bug and not a TWiki one.

-- MeredithLesly - 10 Jul 2006

See FirefoxStylesheetCachingProblem which describes this - you can also force a reload to work around this, which is quicker than clearing the cache. It is indeed a Firefox issue.

FirefoxBrowserIssues and BrowserIssues are the places to look for browser issues that affect TWiki usage.

-- RichardDonkin - 18 Jul 2006

Note that the downloaded TWiki-4.0.4 should be updated with hotfix 4. If you have applied hotfix 3 it is important that you upgrade it to hotfix 4 right away because Bugs:Item2859 can create hours of manual repair work on topics where people have uploaded attachments with Internet Explorer. It is not unsafe but very annoying.

-- KennethLavrsen - 14 Sep 2006

I am trying to download TWiki 4.0.4, it is seen as 4.90 MB, it says download completed, but each time I download I get files whose size are 3MB, 1.3MB etc. So I can't extract it since the file is corrupted. Same occurs in tgz also. Anyone can help me?

-- OnurSencer - 20 Sep 2006

I've solved my problem, if I use a download tool like download accelerator, I can get all file.

-- OnurSencer - 20 Sep 2006

I'm trying to install 4.0.4, everything works fine with twiki/bin/configure but when I'm finished and try to see the page at twiki/bin/view I just get a blank page, no errors... I already cleared the browsers cache (its firefox) but still doesn't work...

-- PedroFerreira - 04 Oct 2006

I was using Firefox, I just tryed with IE 6 and I have a page with error message HTTP 500 - Internal server error. Strange, firefox displays a blank page and doesn't complain, IE displays an error page...

-- PedroFerreira - 04 Oct 2006

If I turn off the "Friendly HTTP error messages" in tools - internet options - advanced then I get the same behaviour as Firefox, a blank page and no erroers... I'm tired... I'm going home...

-- PedroFerreira - 04 Oct 2006

Please ask support questions in the Support web, thanks.
