登陸DEDECMS后臺輸入用戶名和密碼后沒有提示顯示為空白,主要原因是php5.4的版本刪除了session_register函數,打開文件include/userlogin.class.php在 function keepUser()內把如下代碼:

1. @session_register($this->keepUserIDTag); 
2. $_SESSION[$this->keepUserIDTag] = $this->userID; 
3. @session_register($this->keepUserTypeTag); 
4. $_SESSION[$this->keepUserTypeTag] = $this->userType; 
5. @session_register($this->keepUserChannelTag); 
6. $_SESSION[$this->keepUserChannelTag] = $this->userChannel; 
7. @session_register($this->keepUserNameTag); 
8. $_SESSION[$this->keepUserNameTag] = $this->userName; 
9. @session_register($this->keepUserPurviewTag); 
10. $_SESSION[$this->keepUserPurviewTag] = $this->userPurview; 
11. @session_register($this->keepAdminStyleTag); 
12. $_SESSION[$this->keepAdminStyleTag] = $adminstyle; 
13. //開源軟件:Vevb.com 
14. //替換成 
15. $_SESSION[$this->keepUserIDTag] = $this->userID; 
16. $_SESSION[$this->keepUserTypeTag] = $this->userType; 
17. $_SESSION[$this->keepUserChannelTag] = $this->userChannel; 
18. $_SESSION[$this->keepUserNameTag] = $this->userName; 
19. $_SESSION[$this->keepUserPurviewTag] = $this->userPurview; 
20. $_SESSION[$this->keepAdminStyleTag] = $adminstyle; 

即把每個包含@session_register的語句刪除,即可以解決該問題,或者換成其他版本的php.
