I am using D7.

I have strange problem with meta tags. For some content type even if I enter meta title, meta keywords and description , they don't get effective on page.

Where in for some content type it does reflect the meta information.

Can someone help me how can I narrow down the problem in D7. I have no idea how can I make use of meta tag quick module for my problem because meta information is not getting generated..

Can someone share how can I debug where exists the problem.

Thanks
