Hi,
The details of the “Server Error” screen said “when capturing https://XXXXXXX/wp-admin/edit.php?action=event_duplicate&event_id=10&_wpnonce=06282f19de
, an error is encountered. The site may be down for maintenance or configured incorrectly.
Error Code: 500″.
I turned on wp_debug, and there were three message:
1.Notice: add_custom_image_header is deprecated since version 3.4! Use add_theme_support( ‘custom-header’, $args ) instead. in /XXXXXXXXXXXXXX/wp-includes/functions.php on line 2900
2.Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent (output started at /XXXXXXXXXXXXXX/wp-includes/functions.php:2900) in /XXXXXXXXXXXXXX/wp-includes/plugin.php on line 406
3.
Fatal error: Class ‘EM_Tags’ not found in /XXXXXXXXXXXXXX/plugins/events-manager/classes/em-event.php on line 780
Did the third error related with the previous two?
I found the first error may be caused by my old theme.
But I tried to use a lasted theme, and the EM copy error still occured.
Thanks!
