I only get background on the homepage, not on any other page.
The code for the background is inserted in "Body, text and links"

background: url(wp-content/themes/atahualpa342/images/mod/center-strip.jpg) repeat top center;

Look at:
http://85.118.206.30/~ftxabse/wp/

Greatful for some ideas about it!

try putting in the full http address i.e.
background: url(http://85.118.206.30/~ftxabse/wp/wp-...nter-strip.jpg) repeat top center;

It worked perfect!

Thank's a LOT!
