解決 Discuz！X3.4以下版本前臺打開卡慢、後臺登陸卡死或504錯誤等問題
discuz的新版本檢測和補丁功能已經關閉，導致後臺調用相關連接超時，引起後臺打不開X3.4已經移除相關代碼，沒有此問題，建議升級

X3.4以下的版本解決辦法
後臺
打開：source/admincp/admincp_main.php
删除（大概在37-60行）
if($_G['uid'] && $_G['member']['allowadmincp'] == 1 && ($_G['setting']['showpatchnotice'] == 1 || !isset($_G['cookie']['checkpatch']))) {
$discuz_patch = new discuz_patch();
if($_G['setting']['showpatchnotice'] == 1) {
$notice = $discuz_patch->fetch_patch_notice();
if($notice['data']) {
$shownotice = '<div class="notice"><a href="'.$basescript.'?action=patch" id="notice">'.($notice['fixed'] ? $lang['patch_fix_complete'] : $lang['patch_fix_rigth_now']).'</a></div>';
}
}
if(!isset($_G['cookie']['checkpatch'])) {
$discuz_patch->check_patch();
}
}
if($_G['uid'] && $_G['member']['allowadmincp'] == 1 && !$shownotice && $_G['setting']['upgrade']) {
$shownotice = '<div class="notice"><a href="'.$basescript.'?action=upgrade" id="notice">'.$lang['upgrade_right_now'].'</a></div>';
}
if($_G['uid'] && $_G['member']['allowadmincp'] == 1 && !isset($_G['cookie']['checkupgrade'])) {
$discuz_upgrade = new discuz_upgrade();
if($discuz_upgrade->check_upgrade()) {
if(empty($shownotice)) {
$shownotice = '<div class="notice"><a href="'.$basescript.'?action=upgrade" id="notice">'.$lang['upgrade_right_now'].'</a></div>';
}
}
dsetcookie('checkupgrade', 1, 7200);
}
前臺
也有影響管理員打開速度的
下載替換文件 source/module/misc/misc_patch.php
也就是只保留IP異常提醒的代碼，用不到也可以刪了
