解决方法
1.打开 source/admincp/admincp_main.php

2.从第37行至60行的代码全部删除或者屏蔽

删除如下代码
  1. if($_G['uid'] && $_G['member']['allowadmincp'] == 1 && ($_G['setting']['showpatchnotice'] == 1 || !isset($_G['cookie']['checkpatch']))) {
  2.     $discuz_patch = new discuz_patch();
  3.     if($_G['setting']['showpatchnotice'] == 1) {
  4.         $notice = $discuz_patch->fetch_patch_notice();
  5.         if($notice['data']) {
  6.             $shownotice = '<div class="notice"><a href="'.$basescript.'?action=patch" id="notice">'.($notice['fixed'] ? $lang['patch_fix_complete'] : $lang['patch_fix_rigth_now']).'</a></div>';
  7.         }
  8.     }
  9.     if(!isset($_G['cookie']['checkpatch'])) {
  10.         $discuz_patch->check_patch();
  11.     }
  12. }
  13. if($_G['uid'] && $_G['member']['allowadmincp'] == 1 && !$shownotice && $_G['setting']['upgrade']) {
  14.     $shownotice = '<div class="notice"><a href="'.$basescript.'?action=upgrade" id="notice">'.$lang['upgrade_right_now'].'</a></div>';
  15. }
  16. if($_G['uid'] && $_G['member']['allowadmincp'] == 1 && !isset($_G['cookie']['checkupgrade'])) {
  17.     $discuz_upgrade = new discuz_upgrade();
  18.     if($discuz_upgrade->check_upgrade()) {
  19.         if(empty($shownotice)) {
  20.             $shownotice = '<div class="notice"><a href="'.$basescript.'?action=upgrade" id="notice">'.$lang['upgrade_right_now'].'</a></div>';
  21.         }
  22.     }
  23.     dsetcookie('checkupgrade', 1, 7200);
  24. }
