Solution for - Fatal error: Call to undefined function wp_get_current_user() in /wordpress/wp-includes/capabilities.php on line 1183

After the release of WordPress Data Guard Pro Plugin (Version 2.9), few users reported that they are getting the error like :

Fatal error: Call to undefined function wp_get_current_user() in C:\xampp\htdocs\wordpress\wp-includes\capabilities.php on line 1183

Solution:
If you run into the same problem, then there is a simple solution for it.

Just write the below code in wordpress/wp-includes/capabilities.php after ?php sign.

require_once("pluggable.php");

Now you will be able to load all the pages without any error.

So, What is the exact problem :
This problem arises when one of your plugin or theme file wants to get the user type (e.g. Administrator, Editor, Contributer, Author, Subscriber) either in form of a function or in form of variable.

For Example, the below code will generate the same error, if placed in a plugin file:

if(current_user_can('level_10')) {$user_is = 'Admin';} else {$user_is = 'Not Admin'; }

So in such cases, you can include the pluggable.php file into capabilities.php file.

Note : You might bookmark this page for the future references, as after updating the wordpress, capabilities.php gets restored to default, and then you need to follow the same procedure again.
