My wp-admin and not working

Question

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

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

I tried all possible ways to fix it, but I can not fix this problem, so I need your help. I have tried:

• Change the default theme.
• Deactivation of plugins.
• Reconfiguring the WP-Config.php file.
• Wp-debug value, true.
• In addition, a private tag has been added to the function.php file.

Friends my project works well in the local host and live the project works, but its backend does not work

Answer 1

There are several possible situations that can create this error:

• UTF-8 => Your UTF-8 files? no specification (did you open live files with Notepad ++?), more information about this problem
• Delete all plugins , try logging in again (to make sure the plugin does not create "headers already sent ...)
• The same goes for Themes
• remove closure ?> in functions.php

Answer 2

In functions.php remove ?> From the end if it exists.

Answer 3

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

Finally, my site is live, and I am very happy for this and thank everyone who helped me in solving my problem.

Answer 4

To fix the error:

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

Hope this helps you.
