the code for the store message pod is in the webassist/themes/crazy/templates/index.dwt.php:
<div id="banner" class="ps_main ps_pod4">
<div class="block ps_highlight">
<div class="info">
<h1><?php echo WA_getCMSContent($database_PowerStoreConnection, $PowerStoreConnection,"Home Page", "Site Message"); ?></h1>
<?php echo WA_getCMSContent($database_PowerStoreConnection, $PowerStoreConnection, 'Middle Pod' , 'Content'); ?>
</div>
<div class="preview">
<img id="bannerImage" src="../images/example.featured.png" alt="Featured product" />
</div>
</div>
</div>
you can remove the image by editing that code to:
<div id="banner" class="ps_main ps_pod4">
<div class="block ps_highlight">
<div class="info">
<h1><?php echo WA_getCMSContent($database_PowerStoreConnection, $PowerStoreConnection,"Home Page", "Site Message"); ?></h1>
<?php echo WA_getCMSContent($database_PowerStoreConnection, $PowerStoreConnection, 'Middle Pod' , 'Content'); ?>
</div>
<div class="preview">
<!--<img id="bannerImage" src="../images/example.featured.png" alt="Featured product" />-->
</div>
</div>
</div>
In the Crazy theme, the "middle pod" content is the content area displayed bellow the featured product and most popular product pod, in your site, this pod is empty right now.
making the webassist/plugins/catalouge/popularbox.php file a blank page will remove the content from the most popular box, if this is not changing in your site, it would suggest that the changes are not making it up to the server.
