When using the Events Manager plugin for WordPress, you may encounter a problem where $EM_EVENT becomes NULL. This is caused by the fact that under certain conditions, event data cannot be retrieved properly.
It has been reported that this problem does not occur after calling the_title() function. However, this is not a stable solution. As a more reliable method, it is recommended to explicitly retrieve the event object using the em_get_event() function.
$event = em_get_event(get_the_id());Using this method effectively avoids the problem of $EM_EVENT being NULL. Choose the appropriate method depending on the situation and aim for stable event management.
