[xwiki-users] Problems with creating pages

Hi! Some users noticed a problem by creating a new page. If they want for example create a page with the name: "Tutorial: How to use Windows" we get the following error: Error number 4001 in 4: Error while parsing velocity page /templates/create.vm Wrapped Exception: Failed to evaluate content with id [/templates/create.vm] At first I tried to change the coding to UTF-8 in web.xml in WEB-INF to UTF-8 but nothing changed. How can I fix this problem? Florian
