Hi EE,
When i or a customer try’s to download the PDF invoice the site redirect to the homepage without css, and the PDF will not download/generated.
The link created is https://www.domain.nl/?ee=msg_url_trigger&snd_msgr=pdf&gen_msgr=html&message_type=invoice&context=purchasertoken=1-5ef9e8ca62b9c7f5aa7907c06755268e&GRP_ID=2&id=0

I did changed the invoices templates but it worked in the beginning.

Now i disabled all the non EE plugins without results.
Last versions WP and EE plugins.
Could you please help, thankyou

Hi there,

Can you check with your host that the request isn’t being blocked on their end by some form of security, maybe a mod_sec rule?

Hi Tony,
Well im sort of the host. Not sure about mod_sec
Is there a way i can send you i private message with the php info of the server?
I dont see any error logs with debug enabled. Only a POST request.
PHP7 enabled now but with the same result.

What stack are you using?

Is there a way i can send you i private message with the php info of the server?

phpinfo() output won’t really help but you can send details to support[at]eventespresso.com

You currently have caching enabled on the site, try clearing the cache, then temporarily disabling all caching. Does that help?

If you have set up a clean install, with no other plugins to conflict with and your using a default theme such as twentyseventeen with the same problem then it’s unlikely a login to the site will help as its more likely to be a server config issue.

If you are the host you should be able to check if mod_security is enabled within Apache?

hi Tony,

mod_security is not enabled on the server. No other plugins, default theme, default event espresso settings. Debug on true. I don’t see any errors in the httpd logfiles. Download button returns this url:

Hmm, ok.

Can you send me temporary login details for the site so I can take a look (I still suspect this is a server config issue but will take a quick look over the site to see if anything stands out).

To send, you can use this form: https://eventespresso.com/send-login-details/

I replied via email with details on this but just wanted to update the thread for future readers.

The problem here is due to the version of libxml installed on the server, we use DOMPDF to generate the PDF’s through EE, look at this issue on their repo:

https://github.com/dompdf/dompdf/issues/1494

There seems to be an issue with later versions of libxml.

The ticket suggests removing all whitespace between the HTML tags to workaround this (which works) so we will likely include in the next version of Event Espresso 4.

The idea Tony shared about removing all whitespace between HTML tags was included in the latest version of Event Espresso 4.
