You can view the broken page then manually change the URL in the address bar to get to its edit page; change the text "page.view" to "editWiki.view". In other words, if your URL were:

    http://localhost:8080/labkey/wiki/home/page.view?name=test

...you would change it to:

    http://localhost:8080/labkey/wiki/home/editWiki.view?name=test

From there you can fix the page or delete it entirely.

We should provide a better wiki management page, one that lets you edit or delete any wiki without viewing it first. I'll add this to the list.
