Domain and index.php … showing something different…

Ok. having a problem …

If I go to…
http://ridgewood.tipsfromtown.com/
… then you will see NO RIGHT COLUMN

But it you go to http://ridgewood.tipsfromtown.com/index.php …
Then you see a RIGHT COLUMN.

in my page.php (which is the default template page), I have the following…

<?php
// This calls the right column include from page.php
if( !is_page(array(12641, 'local-deals', 'Local Deals')) && !is_page(array(7645, 'calendar', 'Calendar of Events')) ) {
 	get_template_part('side', 'right');
}
// I dont see anything wrong with that...
?>

And side-right.php has the following…

<?php
// If It's the homepage, show weather widget.
// NOTE: The widget appears on
// ridgewood.tipsfromtown.com/index.php
// but not ridgewood.tipsfromtown.com/
 if(is_front_page() || is_home()) { ?>
        <!-- weather? -->
        <?php
         // If Weather Plugin (Wunderground) is active ...
         if (is_plugin_active('wunderground/wunderground.php')) {
        ?>
            <div class="right-banners">
                <?php echo do_shortcode("[forecast]"); ?><br /><br />
            </div>
        <?php
         }
        ?>
<?php } ?>

// Then NO CONDITIONS. The page should show this ... but it doesn't
     <div class="right-top">Our Friends</div>
	<div class="right-banners">
        // ...
        // OTHER CODE
        // ...
        </div>
      </div>

Note … the index page shows the weather widget, and the OUR FRIENDS. However, the non-index view shows the comments <!– –> for the weather widget. So, it looks like the code is BREAKING on the weather widget for the non-index page.

Any idea why?
