Problems

Hey guys, I've some problems with Xwiki. In first the Tomcat's log is reporting some errors, see it bellow. Second, I've create a page. After the creation, I decide update this page. I open the the correct place to do that, updated the page and saved. When this page is reloaded, it appear that I don't altered. Can you understand? Tomcat's error: 1º Error (it's a warning, but why this is apearing??): 10:21:50,467 WARN http-8080-Processor5 RequestUtils:createActionForm:177 - No FormBeanConfig found under 'view' 2º Error: 10:22:04,568 WARN http-8080-Processor5 http://localhost:8080/xwiki/bin/view/Main/WebHome Configurator:configure:126 - No configuration found.
