Get your Youtube iframes back in your posts

If you were used to adding iframes or other fancy HTML tags in the content of your posts, and you can't do it anymore it's quite possible that it's because of the DISALLOW_UNFILTERED_HTML constant that has been set to true in the wp-config.php file.

Since this constant is not modified by SecuPress, this modification comes from another plugin or from a manual modification of the wp-config.php file. The purpose of this constant is precisely to forbid the use of HTML without protection, i.e. only certain HTML tags are now allowed. Why is this? Because some tags can be dangerous, notably <iframe> and <script>.

If you still want to get your tags back you can:

  1. Open your FTP
  2. Edit wp-config.php file
  3. Find the ligne about DISALLOW_UNFILTERED_HTML 
  4. Delete it

Now, you can, again, insert your dangerous contents.
