Disable dbmanager and re-enable it, it’ll re-install w/ a new path and that should fix it, also make sure you move that htaccess.txt file into the root of your backup-db folder.

He’s just giving $id a default value it’s meant to be replaced and can help eliminate any PHP Notices that you may get if your server is set up incorrectly. However, considering there would never be a post w/ the value of 0, may as well leave it blank, so that the function will error out if you don’t feed it a proper number, thus requiring you to input an id.

function getPageContent($id)

but either way works fine

From the looks of it, the Modern Clix theme isn’t actually using the post-thumbnail feature. Seems as if you are embedding that featured image in your body. So here are a couple ways to approach it:

1. Use post-thumbnails instead of embedding it in your body:
http://codex.wordpress.org/Post_Thumbnails#Function_Reference

or

2. In the index.php where it says:
<?php the_content('Continue reading...'); ?>

you can change that to something like (untested code):

if ( is_front_page() ):
  echo strip_tags(get_the_content('Continue reading...'), '<p><em><b><a>');
else:
  the_content('Continue reading...');
endif;

There should be an Author drop down at the bottom of each post.

try clearing out everything and only doing
<?php the_content('<br /><br /><span class="readmore-icon">Read the rest of '. get_the_title($post->ID). '</span>', FALSE);?>

see if that give you the excerpt like you want. and notice that get_the_title() only accepts one param, the ID, or nothing and it assumes that the id passing is the id of your current post/page.

Also, I think that if you’re trying to get the excerpt using this method you have to use the “Insert more tag” option in the WYSIWYG which is the icon that looks like two pages separated by a dotted line. I could be wrong, I don’t generally snag the excerpts that way.

then remove the first li
<li><?php comments_popup_link( __('Leave your comment', 'jenny'), __( '1 comment', 'jenny'), __('% comments', 'jenny')); ?> &bull; <?php the_category(' &bull; ');?></li>
