  • The following messages only appears when trying to view certain PDFs.

    ‘Warning: DOMDocument::loadHTML() [domdocument.loadhtml]: htmlParseEntityRef: no name in Entity, line: 48 in /public_html/wp-content/plugins/gravity-forms-pdf-extended/render_to_pdf.php on line 70
    Unable to stream pdf: headers already sent’

    Hi Demoris,

    The headers already sent message is because of the warning above.

    Try turn off errors and see if you can get the PDF to output.

    Also what error does WordPress spit out when the plugin is activated?

    ‘The plugin generated 2 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.’

    I’ve had one other person have a similar problem but he never got back to me with further information. I think I’ll have to get under the hood to help debug this issue. If you could email me at we can discuss it further.
