Links Disappears from Posts.

[devoidfeast]

Hello Fellows,

I have installed Vbulletin V5.1.2.
Here is the image how the landing page of my forum looks like.
Attachment 149736

there are three columns in the attachment, in the third column named as "Latest in Random" the thumbnails are not showing.Each column is a search widget and the thumbnails are generated from videos links embedded to the posts.
the problem is when a post is posted initially the thumbnail is generated and it looks ok but after some time the thumbnail disappears and when you click on the post there shows no links just empty post as follow.(its the first row in the third column named as "Tharparker Pakistan".
