For some reason when posting a link to my blog on Facebook, a sample page description and images appear (link to screenshot image here: http://www.energybites.co.uk/blog/wp-content/uploads/2012/04/BlogPreviewScreenshots.jpg ). I have deleted the sample page from my blog, and the sample page in question is actually from an old theme that I don't even use anymore and have since deleted.
This preview only shows when posting a link to the homepage, individual blog posts work fine.
I am also experiencing an issue when linking to my Contact and Gallery Pages, it seems to show a few HTML tags instead of the page description or text.
Does anyone know what I need to do WordPress or the Editor to change this? Thankyou in advance for any help!
