Hi Vijay, there is error in widget_feature.php, there is unexpected "<" on line 58.
Maybe you could check what you added there? Best way to check is download the file from your host and check it in dreamweaver.

pdrw07, thanks for your assistance, I have checked and Edith the said file. But there is no changes, though I use front page to check and Edith the file.

Thanks.

Yes Adi is right, paste the code here so we could look it.

Thanks you all for your concern. The following is the code you requested.

<?phpfunction widget_sideFeature() { $options = get_option("widget_sideFeature"); $numberOf = $options['number']; $category = $options['category']; $category = "&cat=" . $category; $showposts = "showposts=" . $numberOf . $category ; ?> <?php $featuredPosts = new WP_Query(); $featuredPosts->query($showposts); ?> <?php $i = 1; ?> <?php while ($featuredPosts->have_posts()) : $featuredPosts->the_post(); ?> <h1 class="side"><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h1> <div class="meta"> By <?php the_author() ?> </div> <div class="storycontent <?php if($numberOf == $i) { echo "noline"; } $i++; ?>"> <?php theme_excerpt('25'); ?> </div> <?php endwhile; }function widget_myFeature($args) { extract($args); $options = get_option("widget_sideFeature"); echo $before_widget; echo $before_title; echo $options['title']; echo $after_title; widget_sideFeature(); echo $after_widget; }function myFeature_control(){ $options = get_option("widget_sideFeature"); if (!is_array( $options )) { $options = array( 'title' => 'Feature', 'number' => '1', 'category' => '0' ); } if ($_POST['sideFeature-Submit']) { $options['title'] = htmlspecialchars($_POST['sideFeature-WidgetTitle']); $options['number'] = htmlspecialchars($_POST['sideFeature-PostNumber']); if ( $options['number'] > 5) { $options['number'] = 5; } $options['category'] = htmlspecialchars($_POST['sideFeature-Category']); update_option("widget_sideFeature", $options); }?> <p> <label for="sideFeature-WidgetTitle">Title: </label><br /> <input class="widefat" type="text" id="sideFeature-WidgetTitle" name="sideFeature-WidgetTitle" value="<?php echo $options['title'];?>" /> <br /><br /> <label for="sideFeature-PostNumber">Number of posts to show: </label> <input type="text" id="sideFeature-PostNumber" name="sideFeature-PostNumber" style="width: 25px; text-align: center;" maxlength="1" value="<?php echo $options['number'];?>" /><br /> <small><em>(max 5)</em></small> <br /><br /> <label for="sideFeature-Category">From which category: </label> <?php $options = get_option("widget_sideFeature"); $category = $options['category']; ?> <?php wp_dropdown_categories('name=sideFeature-Category&selected='.$category); ?> <input type="hidden" id="sideFeature-Submit" name="sideFeature-Submit" value="1" /> <p><small><em>(Note: The selected will be excluded from the main content on the index page)</em></small></p> </p><?php}register_sidebar_widget( 'Featured Post', 'widget_myFeature');register_widget_control( 'Featured Post', 'myFeature_control');?>

This the code for the widget - where is the code for the ad code you put in? I'm sure that you have either an extra '<' in the ad code or you inserted your ad code in the wrong place.
