My wp-admin and is not working

Question

I have a problem with my wp-admin as it is saying that:

ERROR: Cookies are blocked due to unexpected output. For help, please see this documentation or try the support forums

I have tried all possible ways to fix it but I am unable to fix this problem so I need your help . The ways I tried are:

1. Changing the theme into default.
2. Deactivating the plugins.
3. Re-configuring the WP-Config.php file.
4. Did Wp-debug value , true.
5. Had given a closing tag in function.php file as well.

Friends my project is running well in localhost and in live the project is running but its backend is not working

Answer 1

在functions.php ，如果存在，请从结尾删除?> 。

Answer 2

There are a few possible situations that are capable of creating this error:

1. UTF-8 => are your files UTF-8? no BOM (have you opened live files with Notepad ++?), more info about this problem
2. Remove all plugins , try again to log in (to make sure there is not a plugin creating the "headers already sent by ...)
3. The same goes for Themes
4. remove the closing ?> in functions.php

Answer 3

I found the answer to my question after long struggle. 1. I put a function in wp-config.php file function : ob_start(); just above my WP-DEBUG function. 2. I changed my hosting service as there was some kind of virus in the server which was automatically changing the file permission of index.php and .htaccess files.

Finally my site is live and I am very happy for that and Thank You everyone who helped me in solving my problem.

Answer 4

To fix the bug:

1. Open file blog/wp-admin/includes/screen.php in your favorite text editor.
2. On line 706 find the following PHP statement: <?php echo self::$this->_help_sidebar; ?> <?php echo self::$this->_help_sidebar; ?>
3. Replace it with the statement: <?php echo $this->_help_sidebar; ?> <?php echo $this->_help_sidebar; ?>
4. Save your changes.

Hope it helps you.
