Editor to share with you after the installation of dedecms background login interface display blank solution, I believe that most people do not understand, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to know it!

Php version: 5.4.4

Everything went smoothly until you logged in to the background and a blank page was displayed after filling in the username and password page. The solution:

Find include/userlogin.class.php, where there is a keepuser () function, which registers a session variable with session_register, but this function has been removed from php5.4. See the official website:

If you use this version of php, you will definitely make an error, but we can modify the following code:

Comment out @ session_register ($this- > keepUserIDTag); and change to

If (! isset ($_ SESSION [$this- > keepUserIDTag]))

There are six of them, all of which are changed to the following:

1 if (! isset ($SESSION [$this- > keepUserIDTag]) 2 / / @ session_register ($this- > keepUserIDTag); 3 $_ SESSION [$this- > keepUserIDTag] = $this- > userID; 4 5 if (! isset ($_ SESSION [$this- > keepUserTypeTag])) 6 / / @ session_register ($this- > keepUserTypeTag); 7 $_ SESSION [$this- > keepUserTypeTag] = $this- > userType; 8 9 if (! isset ($SESSION [$this- > keepUserChannelTag]) 10 / @ session_register ($this- > keepUserChannelTag) 11 $_ SESSION [$this- > keepUserChannelTag] = $this- > userChannel;12 13 if (! isset ($_ SESSION [$this- > keepUserNameTag]) 14 / / @ session_register ($this- > keepUserNameTag); 15 $_ SESSION [$this- > keepUserNameTag] = $this- > userName;16 17 if (! isset ($_ SESSION [$this- > keepUserPurviewTag]) 18 / / @ session_register ($this- > keepUserPurviewTag); 19 $_ SESSION [$this- > keepUserPurviewTag] = $this- > userPurview;20 21 if (! isset ($_ SESSION [$this- > keepAdminStyleTag])) 22 / @ keepAdminStyleTag ($session_register > session_register) 23 $_ SESSION [$this- > keepAdminStyleTag] = $adminstyle

Log in to the background again and you can jump to the management page normally.

PS: about this login background blank problem for a long time, has been unable to find a solution, because not familiar with PHP, the Internet is generally said to be the problem of data/common.inc.php file coding, the encoding to be changed to no BOM format file to save, unexpectedly did not say it is the problem of php5.4, the most important thing is that Weaving Dream official website unexpectedly did not make an explanation, and some people on the official website forum also put forward this question but there is no answer, depressed! But now it's finally solved.
