I am a new alfresco, i installed successfully alfresco, but i can not see any category that is default, same like: Tags, Languages,… When i go "admin console", and create a category, but is fail. I never create a category succesfully, i set up full package with bin file, tomcat 6, alfresco community 4.0.d. Please check on link for issue more (http://awesomescreenshot.com/0f71gd853d). If anybody touch and know about that, Please tell me why?
Check alfresco.log / catalina.out for errors immediately after you try and add a category. You should find a far more detailed error message in either of those files that will help you track down the issue. Feel free to post the error here and people may be able to assist.
