After registering for an event, the Thank You page has a button called “View Full Order Confirmation Recipt”. When I click that button, it opens a new page and shows a fatal error has occurred.
The full error is posted below:
[23-Dec-2022 20:03:14 UTC] PHP Fatal error: Uncaught TypeError: EE_Html_messenger::add_powered_by_credit_link_to_receipt_and_invoice(): Argument #1 ($content) must be of type string, null given, called in /store1/home/yesempower/public_html/wp-includes/class-wp-hook.php on line 308 and defined in /store1/home/yesempower/public_html/wp-content/plugins/event-espresso-core-reg/core/libraries/messages/messenger/EE_Html_messenger.class.php:543

Do you know what version of PHP your site is using?

Hi Garth,
We are on 8.0. I tried switching to 7.4 but had the same error, so we switched back to 8.0.
EE is on the most recent version 4.10.41.p and the Event Espresso – WP Users (EE4.6+) add-on we use is also on the most recent version 2.0.19.p.

Hi there,
Please go to Event Espresso -> Messages -> Default Message Templates.
Find the Receipt message type in the list and click on ‘Edit Purchaser’.
On that page, does it show nothing in the boxes? As in no content to output?
If so, somehow your message template has lost all content and needs to be reset. In the sidebar of that template, you should see a ‘Reset Templates’ button, click that.
Does it show content then?
If so, does that fix the above?

Great! That fixed the issue! The Receipt template content areas were all blank (except for the title). After resetting the template to the default, the receipt link began working again without error.
Thank you so much for your help!
