Oh, sorry. I didn't notice that you've ask about module.
You have to open /modules/mod_jcomments/mod_jcomments.php file and replace:
switch( $show_author ) {
case 0:
break;
case 1:
echo '<br />' . ($label4author != '' ? $label4author . ' ' : '') . $row->name;
break;
case 2:
echo '<br />' . ($label4author != '' ? $label4author . ' ' : '') . ($row->username ? $row->username : $row->name);
break;
}
with
switch( $show_author ) {
case 0:
break;
case 1:
echo ' ' . ($label4author != '' ? $label4author . ' ' : '') . $row->name;
break;
case 2:
echo ' ' . ($label4author != '' ? $label4author . ' ' : '') . ($row->username ? $row->username : $row->name);
break;
}
After this the comment's author name will be shown in same line as comment's date.
