Grey Box on the right side of all pages

[Guest]

I have a grey box roughly 1/3 of the page on all the pages of my pdf that push all content over. when printed it prints like this as well with the grey box on 1/3 of the page.   How can I remove this grey box from all the pages.  Thansk

Looks like it's part of the page. Do you have the paid-for Acrobat or the free Acrobat Reader?
