Hi there,

If you check your servers error logs you’ll find the full error being thrown from the above (your host will usually have a section to view errors in your control panel), can you post that here please?

I’ve just tested a registration (which you can remove if preferred) on Event ID 342 and downloaded the PDF for it without any problems.

Can you link me to an invoice for a test registration that shows the problem?

Ok, so that’s a completely different site to the one linked to your license.

You’re running EE3 and EE4 together, on 2 different sites?

Add this code to the EE4 site’s wp-config.php file: https://eventespresso.com/wiki/troubleshooting-checklist/#wpdebug

Then let me know when its added, or try downloading the PDF again and an errors should be logged to /wp-content/debug.log so we can view them. It’s a fatal error being thrown on the server, but we’ll need that log entry as without it, it could be anything.

Yes, you are right, we use different versions on different site. This is the second account.

Ok, thanks.

That’s fine it just means that the site I tested was the EE3 site, your having an issue with the EE4 site.

I added the code to wp-config. But I don’t see debug.log in /wp-content/. I tried to download invoices multiple times

Just to confirm, you added the code above the line that has:

/* That's all, stop editing! Happy blogging. */

Correct?

It may mean your site can’t create the log file, you can try creating the file yourself via FTP and retesting (if your site can’t create the file it can often write to it once it has been created, but it depends).

Failing that you can swap the code for:

define( 'WP_DEBUG', true );
if ( WP_DEBUG ) {
        define( 'WP_DEBUG_LOG', true );
        define( 'WP_DEBUG_DISPLAY', true );
}

or even just define( 'WP_DEBUG', true );

Then download the PDF and the error should display on the screen (note that with above ALL errors/notices/warnings will be displayed to all visitors so you don’t want to leave that code on the site for long.

Hi,

May I ask is there another plugin activated on the site that also does PDF invoices (or other PDF documents converted over from html)?

It sounds like there is another plugin activated on the site that loads the DOMPDF library (whether it needs it at the moment or not), otherwise you would not get the error you saw.

If you temporarily deactivate all other plugins, then try the PDF does it work as expected?
