Hello Janosch
I have been trying to install Trac and having lot of problem. Then I found these below links and following the instructions to re-install fresh. http://trac.edgewall.org/wiki/CookBook http://trac.edgewall.org/wiki/CookBook/Installation/TracOnWindowsWithAccountManager It seems to work very nice for me so far. And here is the list of plugin: https://trac-hacks.org/svn/ http://trac.edgewall.org/wiki/PluginList I hope you can find some useful information in these link Pink -----Original Message----- From: trac-users@googlegroups.com [mailto:trac-users@googlegroups.com] On Behalf Of Janosch Sent: Wednesday, April 06, 2011 11:04 AM To: Trac Users Subject: Re: Fwd: [Trac] Re: And again: AttributeError: Cannot find an implementation of the "IRequestHandler" interface named "WikiModule". Hi there, can somebody tell me, how modules (like the trac.wiki.web_ui.WikiModule) are beeing loaded in trac? I don't see an import anywhere. What if a module contains errors? Will loading fail silently? I introduced an error in the first line of wiki/web_ui.py and now i get the same result when running tracd (which otherwise works), but no error ('failed loading WikiModule' p.e.) in tracd's console output???
