Vb Api Extension returns data and shows always after <body>
 
I am creating a Api Extension with the help of Wordpress Header & Footer Integation

I am almost done and everything seems to be in order except, whenever I return a data, it always goes on the top of the browser, after the <body> tag, example given below:

PHP Code:
class wpHeaderFooter_Api_Options extends vB_Api_Extensions
{
    public $product = 'wpheaderfooter';
    public $version = '1.0.0';
    public $developer = 'me';
    public $title = 'WordPress Integration Extension';
    public $minver = '5.2.2';
    public $maxver = '5.9.99';
    public $infourl = '';
    public $checkurl = '';
    public $AutoInstall = 1;
    public $extensionOrder = 10;
    
    public function wpHeader($x){
        $path = $_SERVER['DOCUMENT_ROOT'];
           $path .= "/wpfolder/wp-content/themes/mytheme/header-forums.php";
           include_once($path);
           return;
    } 
header-forums.php file simply contains an echo statement. VB displays it, but shows it on the top, even above the main-navbar-wrapper. However, the weird part is, if I do the following, it shows where the hook is supposed to show it

PHP Code:
class wpHeaderFooter_Api_Options extends vB_Api_Extensions
{
    public $product = 'wpheaderfooter';
    public $version = '1.0.0';
    public $developer = 'me';
    public $title = 'WordPress Integration Extension';
    public $minver = '5.2.2';
    public $maxver = '5.9.99';
    public $infourl = '';
    public $checkurl = '';
    public $AutoInstall = 1;
    public $extensionOrder = 10;
    
    public function wpHeader($x){
        //$path = $_SERVER['DOCUMENT_ROOT'];
           //$path .= "/wpfolder/wp-content/themes/mytheme/header-forums.php";
           //include_once($path);
           return "<h1>My Custom Footer</h1>";
    } 
Any help would be highly appreciated.

The echo statement is the problem. VB wants to display the returned data. Assign your data to a variable and return the variable.

$data = '<h1>My Custom Footer</h1>';
return $data;

Well the issue isn't with the second piece of code from my post, outputting the following is causing the issue

PHP Code:
   public function wpHeader($x){ 
        $path = $_SERVER['DOCUMENT_ROOT']; 
           $path .= "/wpfolder/wp-content/themes/mytheme/header-forums.php"; 
           include_once($path); 
           return; 
    }

Using an echo will show at the top of the page like a debug marker. You need to remove the echo.

in your snippet, you're doing "return;"

You need to put the data in a variable and "return $data;"
