Gee, I apologize for the late update, I was able to fix the issue, I followed this solution https://stackoverflow.com/questions/29906595/laravel-5-file-downloads-invalid,
Again, I use laravel. But the method `ob_end_clean` is a generic PHP method, It could help others experiencing the issue even after adding the proper headers. Here's my updated code: 

public function downloadWordDocument($documentId)
{
    try {
        $result = $this->initializeDocument($documentId);
        if ($result) {
            $this->_wordClient->render();
            $document    = $result['document'];
            $shaFileName = $result['sha'] . '.docx';
            $filePath    = Storage::disk('temp')->getDriver()->getAdapter()->getPathPrefix() . $shaFileName;
            $title       = $document->template->enable_prefix ? "{$document->code} {$document->title}" : $document->title;
            ob_end_clean();
            return response()->download($filePath, $title . ".docx", [
                'Content-Type'              => 'application/vnd.openxmlformats-officedocument.' .
                    'wordprocessingml.document',
                'Content-Disposition'       => 'attachment; filename="' . $title . '.docx"',
                'Content-Transfer-Encoding' => 'binary',
                'Content-Length'            => filesize($filePath)
            ]);
        }
    } catch (\InvalidArgumentException $err) {
        return abort(400, $err->getMessage());
    } catch (\Exception $err) {
        return abort(400);
    }
}

Also, How do I filter through all my posts in the forum?.
