custom pdf template failed

Hello, after updating to version 2.X, the customized pdf template cannot show up. use FluentForm\App\Services\FormBuilder\ShortCodeParser; use FluentForm\Framework\Foundation\Application; class certificate extends \FluentFormPdf\Classes\Templates\TemplateManager { public function __construct(Application $app) { parent::__construct($app); } public function getDefaultSettings() { return ['header' => '', 'footer' => '', 'body' => '']; } public function getSettingsFields() { return array(); } public function generatePdf($submissionId, $feed, $outPut = 'I', $fileName = '') { $submission = wpFluent()->table('fluentform_submissions')->where('id', $submissionId)->first(); $response = json_decode($submission->response, true); $htmlBody = ' <div class="description"> test test test </div> '; if (!$fileName) { $fileName = 'certificate -' . $submissionId; } return $this->pdfBuilder($fileName, $feed, $htmlBody, '', $outPut); } } error message as below Uncaught Error: Class \”FluentFormPdf\Classes\Templates\TemplateManager\” not found in /var/www/wp-content/uploads/FLUENT_PDF_TEMPLATES/certificate.php on line 6″,”data”:{“message”:”Uncaught Error: Class \”FluentFormPdf\Classes\Templates\TemplateManager\” not found”,”file”:”/var/www/guide/event/wp-content/uploads/FLUENT_PDF_TEMPLATES/certificate.php”,”line”:6,”trace”:[{“file”:”/var/www/wp-content/plugins/insert-headers-and-footers/includes/class-wpcode-snippet-execute.php(419) : eval()’d code”,”line”:24,”function”:”include_once”} But the code runs well in version 1.111 Thanks! Hi, Sorry for the trouble you are facing. This is a due namespace change in v2. We will add backward compatibility in the next patch (v2.1.1) — custom templates using the old FluentFormPdf\Classes\Templates\TemplateManager class will work automatically. In the meantime, you can fix it immediately by changing line 6 of your certificate.php from: class certificate extends \FluentFormPdf\Classes\Templates\TemplateManager to: class certificate extends \FluentPdf\Modules\FluentForms\Templates\TemplateManager Hope that change will fix your issue. Thank you! It worked!
