Event registration confirmation page no longer shown. Error: Could not find valid value for id.
WordPress 6.2, Civi ESR 5.57.5.
The confirmation page after event registration is no longer shown (for both Test and Live links). Instead, the attached error is shown:-
The workaround is to embed the event registration page as a shortcode. However the confirmation page and confirmation emails show a link to the event info page, which then has the "Register" button taking people to the wrong page.
I'm wondering if this can be fixed, or if we need to override the confirmation and event info pages somehow to redirect users to the WordPress page (perhaps using a naming convention).
Thanks!
