No navigation menu in right column

I'm trying to figure this out as well.

Ok, I figured it out. Open your page.tpl.php file and find this chunk of code:

		<?php if ($right): ?>
		<div id="secondarycontent">
			<!-- secondary content start -->
			<?php print $right?>              
			<!-- secondary content end -->

In the first line, change ($right) to ($sidebar_right)

In the fourth line, change $right to $sidebar_right

The problem is that somehow page.tpl.php for D5.x is replaced with one for D6.x
It could be my fault when I was putting the files in the CVS.

I attached a new page.tpl.php, you can use it instead of existing one or you can easily fix this problem by doing following replacement in existing page.tpl.php line 64:

Replace this:

		<?php if ($right): ?>
		<div id="secondarycontent">
			<!-- secondary content start -->
			<?php print $right?>              
			<!-- secondary content end -->
		</div>
		<?php endif; ?>

With this

		<?php if ($sidebar_right): ?>
		<div id="secondarycontent">
			<!-- secondary content start -->
			<?php print $sidebar_right?>              
			<!-- secondary content end -->
		</div>
		<?php endif; ?>

I will fix this problem as soon as I can release a new version for D5x

(if you want to use the attached file, remember to rename it to page.tpl.php)
