All PERMALINKS have changed!

My web site is a mess! All of my PERMALINKS are now like reflecting a preview of the page even thought the pages are published. Like this – http://www.tech2succeed.com/aboutme/aboutme/?preview_id=1486&preview_nonce=9103c75452&preview=true/watch-this-v/

I don’t know why, but when I go to my website and click on any blog topic I get this message – “You do not have permission to preview drafts.” The pages are not drafts they are published pages. I have searched for a solution, but don’t see one that has worked for me. I have tried 3 different browsers and experience the same message

My website is http://www.tech2succeed.com

Even in the dashboard when I go to VISIT SITE I get the “You do not have permission to preview drafts.” message!

I hope someone can help! thanks!
