Suddenly today, the HEADERS and FOOTERS on my exported PDF documents are no longer working properly, without me doing any changes on the html.

This is example of the HEADER html, which used to create two lines accross my page, and inbetween the two lines my logo on the left side and the filename on the right side. But today, suddenly this same code is only drawing the HEADER for 1/3 of the page, but not stretching across the page as before. Same issue applies to two different spaces, so I suspect some system changes have been made on the OnDeman installation.
