print.css ill

Bonjour,
(L’adresse donnée est un des multiples exemples sur nos 800 blogs utilisant Hueman)

Between october and now, our print.css became ill
Now on a single article, the first page of an article has a sidebar white on the right which cut the text. Not on the second page of the same article.

My print.css

@media print {
  .post-nav,.post-tags,.sidebar,.s1,.s2,.single article ~ * {display: none !important;}
  * {color:black !important;background: none !important;	}
  body {font-size: 10pt;}
  .main-inner{padding-left:0 !important;padding-right:0 !important;}

And because mu plugin we have in another css with :

#cleo, #breadcrumb, #navigation, #sub-navigation, #searchform, #header, #footer, #respond, .WP-PrintIcon, embed, iframe, #openbarre, nav {
display: none;
    }

A blog without sidebar don’t have this problem.
Have i miss some diff in main.css since october ? And how can i resolve this so big problem ˉ\_(ツ)_/ˉ for some of our users ? Thanks
