Listing Page and share button issues

Hi Guys ,

I am facing some issues relating to listing page details and share button in listing page. Pls go to http://www.aboutdehradun.com. and advise a solution.

1) listing page issue: The more info section in a recently added listing is showing no information. The image you see is a gallery image. Refer listing – New Himalayan Electricals
I have even deleted the post and rewrite it but to no good.
Also please see the permalinks. Iam unable to understand why the same is showing when it is set to %post%.

2) The second issue is with the social buttons. When Iam trying to share a listing in facebook it is showing a different thumbnail with the link. Some times the page asks for thumbnail and some times it doesn’t . Why? refer listings – MV Mega Mart

Please suggest a solution . Iam in a big fix now.

Regards,

Narender
