So I think my issue is similar to this ticket or at least my fix was. https://helpdesk.ashanjay.com/ticket/when-i-click-on-an-event-i-receive-the-following-error-there-has-been-a-critical-error-on-this-website/

When I click on an event, the pop up works as expected. However, when I copy event link to clipboard and enter that URL into my tab, I get a critical error has occurred.

This appears in the apache error log when I was using PHP8.0

If I go to a standard theme it works as expected.

I installed PHP7.4 as the linked ticket suggested as the fix and that also did work for me.

So to recap – a direct event link errors out if I’m using the latest version of wordpress ( 6.4.3 ), Avada ( 7.11.7 ), and EventON (4.6) on PHP8.1 and PHP8.0. If I switch to PHP7.4 it works.

I can use PHP8.1 and PHP8.0 if I use a different theme than Avada.
