I am trying to install plugins that's not included in Ikiwiki following instructions at http://ikiwiki.info/plugins/install/. So far I tried http://jblevins.org/git/ikiwiki/plugins.git/plain/h1title.pm and http://ikiwiki.info/plugins/contrib/default_content_for___42__copyright__42___and___42__license__42__/. After putting these .pm files in /home/foo/website/libi/IkiWiki/Plugin and making them executable, I rebuilt the wiki instance. But the plugins aren't working.

Any ideas what might be wrong?

Is there some way to debug?
