Good that you managed to solve your problem.
I did some digging. It seems two problems occurred.
One is that the import process ended in a state where it had no events to review (this may well have been because of the strange characters you mentioned).
The other is that when the plugin tried to report this to you, it failed to generate an error message.
The second is definitely a bug.
In admin/includes/admin-import.php,
where it says:
if(empty($reviewed_events)) {
return new WP_Error('no_events', __('No events found','event-list'));
}
Should become:
$ret = array('success' => 0, 'errors' => array());
if(empty($reviewed_events)) {
$ret['errors'][] = new WP_Error('no_events', __('No events found','event-list'));
return $ret;
}
Also, the later statement in the same method (private function import_events())
$ret = array('success' => 0, 'errors' => array());
may be deleted.
That fix should take care of the error message not displaying, but not of the actual import problem.
Let us hope the plugin’s programmer sees this and provides us with fixes.
