Major problem when update to 7.x.-2.5

Major problem when update to version 7 x -2.5. The site is blocked by a error message.

AFTER UPDATE =

Notice: Undefined variable: page_top in /Volumes/RAID 8/ Pågående Arbeten/_DP_Databaser_lokala/aco2015_dp735/sites/all/themes/adaptivetheme/at_core/templates/maintenance-page.tpl.php on line 30

Recoverable fatal error: Argument 3 passed to menu_tree_prune_tree() must be of the type array, boolean given, called in /Volumes/RAID 8/ Pågående Arbeten/_DP_Databaser_lokala/aco2015_dp735/sites/all/modules/menu_block/menu_block.module on line 375 and defined i menu_tree_prune_tree() (rad 671 av /Volumes/RAID 8/ Pågående Arbeten/_DP_Databaser_lokala/aco2015_dp735/sites/all/modules/menu_block/menu_block.module).
Webbplatsen stötte på ett oväntat fel. Var vänlig försök igen senare.

So I went to line 375 in the "Menu_block.module" file and set the lines 375-381 off. See attached file, here is the lines.

  // Prune the tree along the active trail to the specified level.
/*  if ($config['level'] > 1 || $config['parent_mlid']) {
    if ($config['parent_mlid']) {
      $parent_item = menu_link_load($config['parent_mlid']);
      menu_tree_prune_tree($tree, $config['level'], $parent_item);
    }
    else {
      menu_tree_prune_tree($tree, $config['level']);
    }
  }
*/

Now the site is running, but I don't understand what meaning off the code who no longer is active, it's over my horizon .;)

Can any one please advice if this solution is ok, or if it's possible to adjust what's wrong in the code on the lines 375-381, who creates the error message.

Maybe it's Panel Everywhere and the theme "at_panels_everywhere" who cause the detected problem. I was not able to update "Adaptive theme" on last update, so I am stuck in the older version of the theme, because of setting in the subtheme "at_panels_everywhere".
