I have a Word document where there is a missing page. It jumps from page 23
to page 25 (even on the page counter). How can I fix this so page 25 will go
to page 24 and so on?

Because of that change I will need to change my "Odd page header" to an
"even page header". However, when I try and change this an error message of
"Column widths can not be less than 0.5"." appears. Does anyone know how to
fix this?
