YouTube embeds not working in WordPress after import from Blogger

5 comments

1. …by default, WordPress filters imported XML by removing possible troublesome tags…unfortunateely, including things like <embed> and <iframe> and other instances where you’ve included content in your posts. WordPress does so via a file you can find in /wp-includes called kses.php. In kses.php, you’ll want to scroll down to line 1309 and comment out the three lines under //Post filtering so that they look like this:

   // Post filtering
   #add_filter('content_save_pre', 'wp_filter_post_kses');
   #add_filter('excerpt_save_pre', 'wp_filter_post_kses');
   #add_filter('content_filtered_save_pre', 'wp_filter_post_kses');

2. I think you have a couple of options here:

   1. You could undo the import and
      re-import using another means, from
      RSS for instance. The value of this
      depends on how much effort you have
      in the posts as they are in
      WordPress now – are you willing to
      dump the posts and try again?
   2. You go to the forums, post a bug in
      trac, go to the IRC channel and try
      to find some more information;
      you’re apparently not the only
      person to have this problem
      (unless, of course, that’s you)
   3. if you have db access you could
      update the posts table to add the
      appropriate code back in.
   4. you could manually re-add the embed
      codes (obviously).

   How many posts are we talking about?

3. This all really depends on HOW you imported the blog posts. What was your method?

   When you view the raw source of the posts in wordpress (plain text view) – what does the post look like (a copy of the HTML would be nice)

   — Note – edit your original post to give the answers, a reply doesn’t really work if other people answer too.

4. When I moved from blogger to wordpress my YouTube videos moved over just fine. Martin is right, a view of the post source code is probably required to be helpful.

   One thing to note on a side issue though. When you use the wordpress “blogger importer” the image links will not be updated. When you view your blog everything will look ok, but in fact the images will still be referencing the blogger site.

   There is a plugin on wordpress.org that will help with this, but some manual updating may / will be required for a 100% perfect move.

   I think this is the one I used.

5. Here’s the solution I found on a wordpress forums.

   Find in /wp-includes a file called kses.php. In kses.php, you’ll want to scroll down to line 1309 and comment out the three lines under //Post filtering so that they look like this:

   // Post filtering
   #add_filter('content_save_pre', 'wp_filter_post_kses');
   #add_filter('excerpt_save_pre', 'wp_filter_post_kses');
   #add_filter('content_filtered_save_pre', 'wp_filter_post_kses');
   

   This will prevent the filter from removing all your YouTube videos, SlideShare embed, Scribd documents, etc.
