# Browser Post Version Check

 * [12 years, 11 months ago](https://wordpress.org/support/topic/browser-post-version-check/)
 * WordPress 3.6-RC1-24704
    Browser: Chrome & Firefox
 * Link to a brief screencast video showing how to replicate: [http://www.screencast.com/t/sfxQAf6u](http://www.screencast.com/t/sfxQAf6u)
 * Screenshot of same issue in Firefox: [http://screencast.com/t/j6rEWXtyU](http://screencast.com/t/j6rEWXtyU)
 * Creation of a draft post (and saving the draft) result in the post ID to be added
   to the URL bar (correctly).
 * From that state, restarting the browser or force reloading the tab causes the
   Chrome browser to display MANY copies of the same message.
 * “the backup of this post in your browser is different from the version below”
 * (I believe that error message is specified in wp-admin/includes/misc.php)
 * The problem is really not that the error message breaks anything but that it 
   shows up more than a half dozen times, and pushes the page content way down the
   page.
 * Firefox does not trigger this message so the message itself may be the first 
   error.
 * It does not seem to matter HOW you cause the page to be reloaded (meaning either
   ctrl-F5, or right click reload, or restarting the browser).
 * I should have reported this before as it’s been present since at least beta 4(
   and I think was in beta 3).

 * Haven’t been able to duplicate. So there might be a plugin interaction here.
 * Two issues:
    1. The message shouldn’t show more than once.
    2. The message shouldn’t show at all.

 * [@askkim](https://wordpress.org/support/users/askkim/) what plugins are loaded
   on that screen. Can see something is extending TinyMCE quite a bit, could you
   try disabling and re-testing please.
 * Also if you can look at the page source for errors/irregularities, or even better:
   select view source in the browser, then copy all and paste in a text file, and
   then attach that file to the [trac ticket](http://core.trac.wordpress.org/ticket/24755).
   You can look through the HTML source for information you wouldn’t want to make
   public and delete it, perhaps URLs, paths, etc.

 * I’m looking through plugins now but it’s more than a single plugin interaction
   so I’m having to track down multiples that may be playing a role and look if 
   there are cross reactions too.
 * The extension of TinyMCE is the plugin TinyMCE Advanced and as far as I can tell
   is not my culprit.
 * I may not get this wrapped up tonight but am definitely investigating since after
   Mark mentioned it, I proved that it does not replicate on my test account on 
   the same host.
 * Form what I can tell at the moment, several plugins either cause it or are involved
   in causing it. It may actually be that several plugins cause one copy of the 
   memo to appear and multiple plugins can can cause one instance end up cumulatively
   being additive. Not sure yet.

 * Thanks for checking this out 🙂
 * I’ve tested with TinyMCE Advanced, (it’s one of my plugins btw) and it doesn’t
   cause it. One way this may be happening is if there are multiple H2s at the top
   of that screen. There is a small patch on the trac ticket to prevent this. Perhaps
   if you get a chance, give it a try. The only change needed is in the wp-includes/
   js/autosave.js file on line 636. It currently looks like this:
 * `$('.wrap h2').after( notice.addClass('updated').show() );`
 * and has to be changed to:
 * `$('.wrap h2').first().after( notice.addClass('updated').show() );`.
 * (To test this change you’ll need `define('SCRIPT_DEBUG', true);` in wp-config.
   php).

 * Hmmm… hitting a roadblock. A “half-stack” of my plugins causes one copy of the
   message to turn up inconsistently. Meaning not on every refresh (or even every
   third refresh). I’ve been chasing this for a long while tonight and it’s maddening
   that it’s totally flakey.
 * It *may* be that it’s only turning up after enough time has lapsed to trigger
   an auto-save to kick in.
 * I haven’t given up yet, but calling it a night and will be out of the office 
   the next day or two.

 * PS: Andrew thanks for your plugin awesomeness. I use that plugin on nearly every
   site I own or manage. Good stuff and mucho appreciated 🙂

 * AskKim — any more luck narrowing it down to specific plugins? Alternatively, 
   if you list your plugins for us, we can probably figure it out pretty quickly.

 * same here. this message starts to appear after upgraded to 3.6.
 * This message appears when actively editing a page. It disappears after finishing
   editing the page and leave the page alone for a while.
 * My plugin list is rather short. But the following two might be the reason:
 * – CKEditor
 * – WP Super Cache

 * Hi
 * I’m facing the same problem 🙁 I deactiveted the CKEditor and when clicking on
   the Publish button now the message: **“the backup of this post in your browser
   is different from the version below”** doesn´t appear anymore. Buut, when getting
   back to see all the pages the new page I just created appears like: –SamplePage
 * Any solution so far?
