Hi, 
first of all let me say Thank you for this great CMS. I tested a lot of CMS' and an finally processwire. And I'am really happy that I found it!!! 
It's great to have no templates and create your completly own. I didn't use php before, but with this excellent tutorials, forum posts and some books... It works  
But now I've got one problem: 
I created a page on a local server an everything renderd correct. 
Then I installed processwire on a webserver an recreated all templates, fields and so on (it was't so much, so there were no reasons to backup the local installation). 
But now - I did excactly the same like on the local installation - one div-container is rendered two times. 
And now the strange: One three pages it's wrong and on the 4th page right?!? 
The right one is here, with only one div-container. 
<div class="blog-single-ckeditor">
  <p>content</p>
</div>
The wrong one here (exactly the same template and settings), with two div-containers: 
<div class="blog-single-ckeditor">
  <div class="blog-single-ckeditor">
    <p>content</p>
  </div>
</div>
That's the entry in the template: 
<div class="grauer-hintergrund">
  <div class="blog-single-ckeditor">
    <?php echo $page->ckeditor; ?>
  </div>
  <div style="clear:both;"></div>
</div>
On the localhost, everything was fine... 
So I don't know what I did wrong? Perhaps there are any Ideas. Thank you very much!!!
