 * I setup a Bing webmaster account, and they want me to add the following meta 
   statement in the header:
 * <meta name=”msvalidate.01″content=”84FB9AFAEA2C47CADF801045CA7B39DD” />
 * So I used this plugin, entered the value, then looked at one of my WordPress 
   pages, however there is no meta statement for msvalidate present. Even after 
   I save this value in the WordPress GUI it simply disappears and is instead replaced
   by: <meta />. Very weird plugin behavior.
 * What’s wrong with this plugin?

 * Hello Daniel,
 * You have a typo in the meta statement and it cannot pass the internal validation.
   An empty space is required before `content=`.
 * Correct statement:
 *     ```
       <meta name="msvalidate.01" content="84FB9AFAEA2C47CADF801045CA7B39DD" />
       ```
   
 * Hope this helps,
    George

 * So how is a plugin user supposed to know that there is an internal validation,
   and that a space is required? There is no feedback after I click Save.

 * Hello Daniel,
 * The HTML syntax is the responsibility of the user. Detecting syntax errors like
   a missing space is beyond the scope of the validation that is performed.
 * The internal validation exists for security reasons, mainly to protect the Metadata
   metabox in the post editing screen, where non admins might have access in case
   of a multi-author blog. Nevertheless, it is also used for the plugin settings.
 * The internal validation uses the internal WordPress API and involves serialization
   of the input and removal of invalid content. No feedback is returned to the user
   because the WordPress API returns no such feedback.
 * Unfortunately, there are no plans to implement a custom mechanism that returns
   such feedback to the user.
 * Thanks for your understanding.
 * George
 * PS: I’m marking the topic as resolved. Feel free to re-open.
