 * WordPress Seems to totally affect the Template Hierarchy
 * my if the parent template works perfectly, my child theme, does not work, all
   of my PHP functions does not work.
 * maybe the migration PHP 5.3 to 5.4 affect the web site, but i don’t think so,
   the parent theme, works.
 * i saw in debug mode a new way yo declare WP_Widget.
 * I think i need a really good support on this new version.
 * template hierarchy change the theme links, cause it seems possible to affect 
   a separated part of a them late,.
 * what i have to undestand ?

 * You might want to start by looking at your child theme’s code to make sure none
   of the functions or code in it has been deprecated.
 * If your child theme was written a long time ago it quite possible it has over
   written some of the functions in your parent theme.
 * The code in your child theme would then cause you problems.

 * Version 4.3 introduced a new template named “singular.php” to the Template Hierarchy.
   There were no other changes affecting the hierarchy.
