When trying to view the pdf from the admin area I get this error
Warning: Missing argument 2 for wpdb::prepare(), called in /home/WEBSITE/public_html/wp-content/plugins/gravity-forms-pdf-extended/pdf.php on line 159 and defined in /home/WEBSITE/public_html/wp-includes/wp-db.php on line 990
Unable to stream pdf: headers already sent
Any ideas why?
I’m using your demo form that the plugin creates as a test.
