# jQuery Warning?

 * [12 years, 12 months ago](https://wordpress.org/support/topic/jquery-warning/)
 * Noticed a warning when validating my site’s code and traced it back to the Jetpack
   plugin. This is the warning:
 *     ```
       JQMIGRATE: Logging is active
       JQMIGRATE: jQuery is not compatible with Quirks Mode
       console.trace()
       migrateWarn
       JQMIGRATE: Logging is active
       ```
   
 * Any idea how to fix this? I know it’s not likely hurting anything, but it would
   be nice to have a warning and error free site from time to time.
 * Thanks,
    JMR

 * These notices are not added by Jetpack; the jQuery Migrate plugin is actually
   included in WordPress Core:

 * Okay…thanks.
 * I attributed it to jetpack because the warning only appeared when I had this 
   plugin active.
 * Maybe you know the answer this. I looked up the documentation on warning and 
   it says the one I’m getting is because the site doesn’t have a valide doctype,
   but it definitely does. ([https://github.com/jquery/jquery-migrate/blob/master/warnings.md#jqmigrate-jquery-is-not-compatible-with-quirks-mode](https://github.com/jquery/jquery-migrate/blob/master/warnings.md#jqmigrate-jquery-is-not-compatible-with-quirks-mode))

 * @joelgoodman What happens when you deactivate Jetpack Comments? Does the warning
   disappear?
 * If not, could you start your own thread, and give us more details about the issue?
   Screenshots can also help!

 * [@jeremy](https://wordpress.org/support/users/jeremy/) Herve, yep it does go 
   away when comments are deactivated.

 * @joelgoodman Alright. Then there is nothing to be worried about 🙂 As I mentioned
   to Jon via email, these notices are linked to the Jetpack Comments module. The
   comment form is hosted on WordPress.com and is included in your posts via an 
   iFrame.
 * Inside this iframe, we include different files to allow the comment form to work
   properly, and jQuery is one of them. However, since this file doesn’t start with
   a doctype declaration (it’s a jQuery library), it triggers the notice in your
   browser.
 * Rest assured though; it doesn’t break anything, and won’t create any conflicts
   with other elements on your site.
