This new version of emlog is hard to get used to, and the editor still has a lot of problems!
But I'm not familiar with js, so I can only modify the newline in php!
Find a template for your own article page, for example:echo_log.php
Modify the variables of your article output!

<?
$log_content = str_replace("<br />","</p><p>",$log_content);
echo $log_content;
?>Directly replace the br tag with the p tag!
