I can't changing slug error 404

Hi,

Do you mean the general slug for event posts? Have you tried reapplying your permalinks after changing the slug? Just go to Settings -> Permalinks and press Save Changes.

Thank you for answer.

I have a one question///

how to get startDate & endDate to my website

thank you so much

$startTimestamp = strtotime(get_post_meta($postId, ‘am_startdate’, true));
$endTimestamp = strtotime(get_post_meta($postId, ‘am_enddate’, true));

I found it
Thank you for best Event Post Type Plugin

Good to know you found a solution ??

Just to let you know the plugin comes with ready made template tags for exactly that purpose. For a full list see Template tags under Other Notes.

Here are the ones for getting event dates:

am_get_the_startdate( $format = 'Y-m-d H:i:s', $post = 0 )
am_get_the_enddate( $format = 'Y-m-d H:i:s', $post = 0 )
