我通过编辑/wp includes/capabilities修复了这个问题。php

代码是

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 );
}

function current_user_can( $capability ) {
    $current_user = wp_get_current_user();

    if ( empty( $current_user ) )
        return false;

    if (is_admin())
        return true;
    $args = array_slice( func_get_args(), 1 );
    $args = array_merge( array( $capability ), $args );

    return call_user_func_array( array( $current_user, \'has_cap\' ), $args );
}
