No post found

I now have a perfect preview, added the code to my page and it doesn’t work!

Hi, Can you send link to screenshot of tab Filter Settings?

I am also having this problem. I have two content views each for one category, but despite there being many post for each, they each produce No posts found.
Here is a screen capture of the Filter Settings:

Thanks in advance

Dear afrij,
Thank you for your screenshot.
I see you set 8 as value of Include only setting => CV will show only post which has ID is 8. And it is reason of No post found problem.
Please clear value of Include only setting.
Best regards,

Thank you PT Guy.
But I don’t understand. I want only posts of ID 8 to show. If I remove the number 8, what would show?
Thanks in advance for your patience in helping me.

fixed mine

Dear afrij,

If I remove the number 8, what would show?

=> According to your settings, it will show 12 latest posts.

Hi PT Guy, Yes, when I remove 8 from Include only field, it shows posts, however, I need two pages, one that can show every thing except category ID 8 and another to show only category ID 8.
When I put 8 in the Exclude field, those post with category ID 8 still appear.
I have the lasted WordPress version 4.5.2. I hope you can help me.

Wait, it seems to be working now with using the exclude field only. Thanks!
