Re: {maketoc} results in empty page
maketoc isn't a separate plugin, so there isn't a wikiplugin_maketoc.php file and it isn't in the plugins list; it's just wiki syntax that is input by hand. You should see it listed in the edit help popup's wiki syntax section, along with toc, as syntax for "Table of contents". Any parameters (search doc.tiki.org for details) also need to be input by hand.
