Question

Hello, I finnally got Twiki installed. I can browse around just fine but whenever i try to make any changes including those I make to users I get the following error.

TWiki detected an internal error - please check your TWiki logs and webserver logs for more information.

Base class package "HTML::Parser" is empty. (Perhaps you need to 'use' the module which defines that package first, or make that module available in @INC (@INC contains: path . path-linux-thread-multi path path-linux-thread-multi path path path path path path path-linux-thread-multi path path path path path path path path-linux-thread-multi path path).

I checked the log files and there is on entry for about the time i tried the change but it is incredibly long. If you would like to see it please tell me.

If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

It appears that you need to install the Perl module HTML::Parser. I'm not sure about how the package is called in Fedora, could be perl-HTML-parser or libhtml-parser-perl.

Background: The WYSIWYG editor of TWiki 4.2 needs HTML::Parser. The dependency is listed on WysiwygPlugin, and its existence ought to be checked during bin/configure. Maybe that's simply missing from some dependency list in WysiwygPlugin...

I also try to edit pages, I get error message: Error 500, Internal Server Error. Same things happens when i try to create a new topic.

Jagjit: What was the error log message?

I had the same problem. I figured out that this is because HTML::Parser cannot be installed properly. I had finally worked around the problem using the comments on: http://ubuntuforums.org/showthread.php?t=345820

You can check whether the depended modules are installed by : perl -MHTML::Parser -e 1, if you did not get any output from this command, then it has been installed. Otherwise, you can simply install it by apt-get install libhtml-parser-perl
