I have installed and used the wiki plugin created few first test wikis and have a problem with subwikis. whenever I create new wiki without a parent wiki, it appears in the page without a problem, but any subwiki is breaking the layout completely. Any idea, hint what could be causing the problem? Seems the include of the wiki content doesn't work well, but so far I haven't found the problem cause. I would be thankful for any kind of help.
