Hi!
First of all - great forum

. Bought it for my girlfriends site a few days ago and been busy seitting it up and testing it. Since I am a php web-developer it was more fun choosing the PHP version

.
Found what I think is a bug + fixed it. Not sure if this should go into the other bug forum or not.
Present in the 5.4.3php
Bug: When you set the forum to threaded mode and expanded view as default it still displayes collapsed for a new user. When you check up the theme-admin it is selected as collapsed, even though you have selected expanded.
When looking at the theme.inc.php I noticed that it said:
// Default posts and reply listing to collapsed or expanded
$theme['threaded'] = "threaded";
instead of
// Default posts and reply listing to collapsed or expanded
$theme['threaded'] = "expanded";
So, the bug is in the admin/edittheme.php file.
Solution:
Find
Default postlist format. Collapsed (only show main topic with total number of replies. Expanded (Show topics with a threaded list of all replies):<br>
<select name="threaded" class=formboxes>
<option value="collapsed" $threadedcollapsed>Collapsed mode
<option value="threaded" $threadedexpanded>Expanded mode
</select>
and change to
Default postlist format. Collapsed (only show main topic with total number of replies. Expanded (Show topics with a threaded list of all replies):<br>
<select name="threaded" class=formboxes>
<option value="collapsed" $threadedcollapsed>Collapsed mode
<option value="expanded" $threadedexpanded>Expanded mode
</select>
Now it works
