# WordPress 3.6 and jQuery.BlockUI Version problem – solution

 * I saw that many people have been having some issues with jQuery.BlockUI versions
   after upgrading to WordPress 3.6. So did I. Having looked into it, this is what
   I discovered (and fixed) in my setup.
 * 1. WordPress 3.6 uses the newer (latest) version of jQuery, which is 1.10.2.
 * 2. Lots of plugins use a function call jQuery.BlockUI which requires jQuery 1.2.3
   or above.
 * 3. Now, 1.10 IS higher than 1.2, but older versions of the jQuery.BlockUI code
   used by plugins have a little ‘buglet’ – the code tests for versions BUT drops
   the trailing ‘0’, so instead of asking is 1.10 greater than 1.2, it tests if 
   1.1 is greater than 1.2, and so it fails.
 * 4. This is NOT a WordPress problem – WordPress 3.6 merely uses the latest version
   of jQuery. Previous versions up to 1.9 would obviously pass the buggy test in
   jQuery.BlockUI code.
 * 5. The answer is NOT to downgrade jQuery in WordPress. Well – that might work,
   but don’t do it!
 * 6. The answer is to get your PLUGIN provider to update their plugin.
 * 7. My plugin used a file called wf-an-jqery-plugins.js. Inside that file was 
   a chunk of jQery.BlockUI code that said it was v2.39.
 * 8. I went to the following link for the latest jQuery.BlockUI code (v2.64) and
   then just replaced the v2.39 code in that plugin file with the code from this
   link. Hey presto, it all works again: [http://malsup.github.io/jquery.blockUI.js](http://malsup.github.io/jquery.blockUI.js)
 * 9. So, folks, find out which plugins you have that are using OLDER jQuery.Block
   UI code and have your plugin provider update it – and in the meantime if you 
   understood what I wrote above, perhaps you can fix your plugin(s) yourself.
 * I hope this helps.

 * Thanks for the tips everyone. Anthologize was also the culprit for me. I haven’t
   been using it either but I’ll message the author.

 * The plugin causing issues by me is [_WP Deals_](http://wordpress.org/plugins/wp-deals/)
   and the infringing file is wpdeals_plugins.js found in the “wpdeals-assets > 
   js” folder i tried replacing the entire file with a renamed jquery.blockUI.js
   but its to different. Do i need to have the author rewrite it?
 * sorry if i’m asking for help in the wrong place, and if i am please redirect 
   me.

 * I’m sorry to say that I did what you said but I still have the same problem with
   plugin All-in-One Calendar by Then.ly
 * I found the file in wp-content/plugins/all-in-one-event-calendar/app/view/admin/
   js/
 * and replaced it with the one you mentioned but that didn’t solve the issue…
