I have a personal subscription of the Event Espresso plugin. When I try to edit and save any message template, I got the critical error. Below is what I got from the error log:
[06-Jun-2021 20:39:04 UTC] PHP Fatal error: Uncaught TypeError: Unsupported operand types: string + float in /my hosting directory/wp-content/plugins/event-espresso-core-reg/core/third_party_libs/dompdf/src/Renderer/Inline.php:153
This looks like an error with using PHP8 when viewing the Receipt PDF.
I’ll create a ticket for this, however, for the time being, you’ll need to switch the version of PHP in use on your site to PHP7.X (your host should be able to help you with this).
