Cherry Framework 3.1.5 Incompatible?

I started looking around and I believe my challenge may be in the theme-function.php file. Here is what I found:

$src = wp_get_attachment_image_src( get_post_thumbnail_id( $post_id ), array( ‘9999’,’9999′ ), false, ” );
$thumb = get_post_thumbnail_id();
$img_url = wp_get_attachment_url( $thumb, ‘full’ ); //get img URL
$image = aq_resize( $img_url, 700, 460, true ); //resize & crop img

and

// thumbnail of WP 2.9
$thumbnail_id = get_post_meta( $post_id, ‘_thumbnail_id’, true );

Not sure what to replace and what to replace it with.

I have narrowed my issue down to this set of code:

$post_id        = $posts[$j]->ID;
				setup_postdata($posts[$j]);
				$excerpt        = get_the_excerpt();
				$attachment_url = wp_get_attachment_image_src( get_post_thumbnail_id($post_id), 'full' );
				$url            = $attachment_url['0'];
				$image          = aq_resize($url, $thumb_width, $thumb_height, true);
				$mediaType      = get_post_meta($post_id, 'tz_portfolio_type', true);
				$prettyType     = 0;

				if ($count > $columns) {
					$count = 1;
					$output .= '<ul class="posts-grid row-fluid unstyled '. $custom_class .'">';
				}

				$output .= '<li class="'. $spans .'">';
					if(has_post_thumbnail($post_id) && $mediaType == 'Image') {

						$prettyType = 'prettyPhoto-'.$rand;

						$output .= '<figure class="featured-thumbnail thumbnail">';
						$output .= '<a href="'.$url.'" title="'.get_the_title($post_id).'" rel="' .$prettyType.'">';
						$output .= '<img  src="'.$image.'" alt="'.get_the_title($post_id).'" />';
						$output .= '<span class="zoom-icon"></span></a></figure>';
					} elseif ($mediaType != 'Video' && $mediaType != 'Audio') {

						$thumbid = 0;
						$thumbid = get_post_thumbnail_id($post_id);

						$images = get_children( array(
							'orderby'        => 'menu_order',
							'order'          => 'ASC',
							'post_type'      => 'attachment',
							'post_parent'    => $post_id,
							'post_mime_type' => 'image',
							'post_status'    => null,
							'numberposts'    => -1
						) ); 

						if ( $images ) {

							$k = 0;
							//looping through the images
							foreach ( $images as $attachment_id => $attachment ) {
								$prettyType = "prettyPhoto-".$rand ."[gallery".$i."]";
								//if( $attachment->ID == $thumbid ) continue;

								$image_attributes = wp_get_attachment_image_src( $attachment_id, 'full' ); // returns an array
								$img = aq_resize( $image_attributes[0], $thumb_width, $thumb_height, true ); //resize & crop img
								$alt = get_post_meta($attachment->ID, '_wp_attachment_image_alt', true);
								$image_title = $attachment->post_title;

								if ( $k == 0 ) {
									if (has_post_thumbnail($post_id)) {
										$output .= '<figure class="featured-thumbnail thumbnail">';
										$output .= '<a href="'.$image_attributes[0].'" title="'.get_the_title($post_id).'" rel="' .$prettyType.'">';
										$output .= '<img src="'.$image.'" alt="'.get_the_title($post_id).'" />';
									} else {
										$output .= '<figure class="featured-thumbnail thumbnail">';
										$output .= '<a href="'.$image_attributes[0].'" title="'.get_the_title($post_id).'" rel="' .$prettyType.'">';
										$output .= '<img  src="'.$img.'" alt="'.get_the_title($post_id).'" />';
									}
								} else {
									$output .= '<figure class="featured-thumbnail thumbnail" style="display:none;">';
									$output .= '<a href="'.$image_attributes[0].'" title="'.get_the_title($post_id).'" rel="' .$prettyType.'">';
								}
								$output .= '<span class="zoom-icon"></span></a></figure>';
								$k++;
							}
						} elseif (has_post_thumbnail($post_id)) {
							$prettyType = 'prettyPhoto-'.$rand;

Hi!

As discussed in other support threads and in the FAQ, the plugin only works with themes that use the function (get_)the_post_thumbnail to print the featured image. Your theme uses a different set of functions: get_post_thumbnail_id and wp_get_attachment_url.

In order to fix the issue, the only thing you can do is identify the locations in which your theme uses those functions and add an if condition before them, so that it uses the external featured image.
