I upgraded to EM 7.3.1 from recovery mode which resolved the problem of WP-Admin crashing.

I generated a new event. It previewed fine in draft, I published and get “Oops! That page can’t be found.” when I follow the link from the events page.

I have tried resetting the permalinks.

WP V7.0 with PHP 8.3.31

The page I need help with: [log in to see the link]
