Fatel Error

Hi,

I’m getting this fatal error:

Fatal error: Call to undefined function wp_get_current_user() in /home/alter4u/public_html/wp-includes/capabilities.php on line 1281

I’ve called my host provider and they said it was something to do with WordPress and couldn’t help me so I’m here hoping to find something or someone that can help.

Does anyone know what this error is and how to fix it?

I can access the individual sites on the multisite but I can’t access the Network Admin Panel – Dashboard to update or do anything there since I can’t access it.

I did look at the 1281 lines on the php file in question but I don’t know enough to do anything here.

Here is the code specifically from 1281:

$current_user = wp_get_current_user();

Here is the code from 1272 to 1290

/**
* Whether current user has capability or role.
*
* @since 2.0.0
*
* @param string $capability Capability or role name.
* @return bool
*/
function current_user_can( $capability ) {
$current_user = wp_get_current_user();

if ( empty( $current_user ) )
return false;

$args = array_slice( func_get_args(), 1 );
$args = array_merge( array( $capability ), $args );

return call_user_func_array( array( $current_user, ‘has_cap’ ), $args );
}

Does anyone know what this error is and how to change/fix the code?

I would like to update the multisite plugins and what not but can’t.

Anyone? Thanks

John
