Hi Florian, On Jul 1, 2008, at 6:20 PM, Florian Rhomberg wrote: When you create a page you have to put the name of the page not the title of the page or a description of the page... So in this case you should name it something like: "TutorialHowToUseWindows" for example or simple "WindowsTutorial" or whatever other name you want to give to that page. You can then set its title either inside the document as a level 1 title with: 1 Tutorial: How to use Windows Or using the title field. Of course we should also fix the error so that it's more user friendly. Basically you're not allowed to use ":" in page names since this is a reserved keyword used to specify that a document is located in another subwiki. For example: subwiki:Space.Page is the Page page located in the Space space in the subwiki Wiki. Please create a jira issue for this so that we can improve it in the future. Thanks -Vincent
