Content type title field not available in manage display I have two customized content types, both having a title field. Yet this field does not appear in the Manage Display panel. Moreover, they are not displayed when the content is displayed.

Is this normal? How can I access those title fields? How can I have them displayed?
It is not normal 
but may be the theme you use does not display page title or you hide it with css
anyway you can go to node.tpl and write echo $node->title to check that
