I am also facing the same kind of problem in my site. I have a homepage with several thumbnails linking to pdf pages. When we go to a specific pdf page, there is no problem.
But when we click on the home button or the header image, we should be reaching the homepage, instead the latest post page opens. I am totally unsure about the reason for this.
I tried all the possible ways to clear this problem viz.
1. Clearing the Cache
2. Changing the Permalinks, etc.
Please help.
