Hi fordonskontroll,
Please try the example below. I used two forms on the same page too,it works fine for me.
<?php require_once "phpuploader/include_phpuploader.php" ?>
<?php session_start(); ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>demo</title>
</head>
<body>
<form name=form1>
<div>
<?php
$uploader=new PhpUploader();
$uploader->MultipleFilesUpload=true;
$uploader->InsertText="Upload File (Max 10M)";
$uploader->MaxSizeKB=102400000;
$uploader->AllowedFileExtensions="jpeg,jpg,gif,png,zip,avi,txt";
$uploader->Render();
?>
</div>
</form>
<form name=form2>
<input type="text" />
</form>
</body>
</html>
If still get the same issue on your end with the example above, please download the latest version and try again.
