Attempting to download a pdf invoice I get the following error:
Warning: DOMNode::cloneNode(): ID invoice already defined in /wp-content/plugins/event-espresso-core-reg/core/third_party_libs/dompdf/include/frame_decorator.cls.php on line 453

Hi,
Do you have WP_Debug or error_reporting enabled on the site? If so can you disable it an retry please?
Please see this thread: https://eventespresso.com/topic/invoice-pdf-button-generating-an-error-when-clicked/
If you have any further questions or disabling error reporting doesn’t work, please let us know.

Neither WP_Debug or error_reporting are enabled on the site.

Hi, could you try setting debugging to off via your wp-config.php file?
I found another member with the same warnings here and it was resolved by setting them to off:

I already have it as the following in my wp_config file
define('WP_DEBUG', false);

Try this macro:

Also be careful of extra spacing in your wp-config.php file as that can cause the headers already sent issue.

Checked for extra spacing and tried the macro but still getting the same errors.

Hi,
Could you re-test on defaults with a default WP theme and only Event Espresso running? Does the issue continue?

we are having the same problem and these suggestions do not work for us either.

Unfortunately I can’t test on the live environment. So I’ll need to set up a staging environment to see if changing to default theme and only EE plugin running resolve the issue. It was working fine previously until the last EE core plugin update.

Our developer just found this:
open this file:
wp-content\plugins\event-espresso-core-reg\core\third_party_libs\dompdf\include
frame_decorator.cls.php
on line 1 add this code:
error_reporting(0);
so it looks like this
<?php
error_reporting(0);
/**
* DOMPDF – PHP5 HTML to PDF renderer
cheers.

You can avoid hacking core files in Event Espresso by adding the following to your wp-config.php file:
@ini_set( 'display_errors', 0 );
