Cannot see page content? I'm building a custom theme for Drupal 7.xx, which is part of my internship.
I've been developing this theme for quite a while now, but I still consider myself an absolute beginner when it comes to theming for Drupal.

During the process, I've ran into quite a few problems which (luckily) I've been able to solve with the help of google (including Drupal Answers) so first of all thanks for that!

One of the problems I seem to be unable to solve, is that I cannot see the page content anywhere. So far I've added all content of the pages in blocks, which I've assigned to be rendered out by a region called 'cont_page_block', and which I have declared in my .info document.

To clarify: When I add a new page, I fill in the page title and body, but it doesn't appear on the page. Also, when I add a news article, I can see the teaser on my 'news summary' but when I try to click on it (which works though) it redirects me to a new page (URL states ?q=node/xx) which is, ofcourse, empty.

Here's the code I use in my page.tpl.php file to render the region:

   &lt;div class="cont_page_block"&gt;    &lt;?php print render($page['cont_page_block']); ?&gt;
                                    &lt;?php print render($content); ?&gt;               &lt;/div&gt;


And here's the declaration of my regions in my .info file:

regions[cont_page_block] = content-page-block  
regions[content] = content


Am I missing a line of PHP code in my page.tpl.php file?
Any help would be greatly appreciated!
Try using:

&lt;?php print render($page['content']); ?&gt;


Edit:
To further the above, if you want to see the action links/titles/tabs you can print those by:

&lt;?php if ($title): ?&gt;
      &lt;h1 class="title" id="page-title"&gt; &lt;?php print $title; ?&gt; &lt;/h1&gt;
      &lt;?php endif; ?&gt;
      &lt;?php print render($title_suffix); ?&gt;
      &lt;?php if ($tabs): ?&gt;
      &lt;div class="tabs"&gt; &lt;?php print render($tabs); ?&gt; &lt;/div&gt;
      &lt;?php endif; ?&gt;
      &lt;?php print render($page['help']); ?&gt;
      &lt;?php if ($action_links): ?&gt;
      &lt;ul class="action-links"&gt;
        &lt;?php print render($action_links); ?&gt;
      &lt;/ul&gt;
      &lt;?php endif; ?&gt;
      &lt;?php print render($page['content']); ?&gt;
      &lt;?php /*?&gt;&lt;?php print $feed_icons; ?&gt;&lt;?php */?&gt;
