I found where’s the problem but it’s very strange, while it serve some of my needs that I can’t get, it although has no thing to do with this!
The problem was in “Vicomi Feelbacks” plugin, when i deactivated it posts showed up in category, although they show as a full post in the home page while it was only show as a title with featured image, I loved the title with the featured image really but I will search another way to do that then i will delete this plugin,
The question is, What the connection between a feed back buttons plugin and all this things?! maybe because it show some related posts after the feed back?!
