WordPress Fix – Add Media Button Not Working

Posted on: December 13th, 2012 by carnfield

Hello everyone and this is a fix for a common issue in WordPress 3.5.

WordPress Fix – Add Media Button Not Working

Basically you’ve just updated your install of WordPress and bang! The Add Media button doesn’t work!  What to do?
Never fear, Carnfield is here – with a fix!

Basically you need to open your “wp-config.php” file in the root of your WordPress Install.
Search for this line:

require_once(ABSPATH . 'wp-settings.php');

And just before it add this code:

define('CONCATENATE_SCRIPTS', false );

Now your WordPress Install should be fixed!

Try disabling all plugins, some times its an issue with the theme too.

Hi, I did place the additional text to my wp-confid.php file and have disabled all my plugins, but still it didn’t work for me. Any additional idea? Thanks

[…] I found a suggestion in this post entry, Plugin not working with WordPress 3.5 which directed me to this trick on this website, Carnfield: WordPress Fix – Add Media Button Not Working. […]

Super answer! Works for me.

Rob says:

Thanks a lot for this fix, it worked. I used WP 3.5 for an entire month and the issue just decided to come out of nowhere this afternoon.

What exactly does that line do, though? I noticed that my WYS pages all load slower, but I don’t see any other downside that’s come from this.

Sunira says:

Oh thank you so much! This worked perfectly!

Thanks so much for this tip to solve this problem. I’m not so technical (yet :-)). Can you please tell me where I can find:
Basically you need to open your “wp-config.php” file in the root of your WordPress Install.

I have a theme installed, i don’t know if that gives additional ‘problems’.

Thanks again for your feedback!

Petra says:

Thanks for your solution to the problem.. I’m not so technical (yet). Can you explain to me where i can find:

Thanks for the effort and reply!

Web Design says:

Hello Petra, you would need FTP access for this, if you try updating wordpress to a newer version it might work without this hack.

Leland says:

Thanks Man its working………… thank you so much.

Tomislav says:

Worked for me, but I would really like to know what did this part of code: “define(‘CONCATENATE_SCRIPTS’, false );” really do ?

Web Design says:

Hi; This disables Javascript Concatenation

Royce says:

Thanks for this fix, it worked! I hope it remains fixed… the WordPress support forums were totally useless. As others have also asked, if you could explain what is inherently wrong with WP3.5.1 that this fix is necessary and what the fix does, we’d appreciate it! Just trying to understand.

Web Design says:

Its to do with the Theme / Plugins that you are using and scripts in easy to understand terms 🙂

Great fix, thanks heaps

Annie Star says:

My problem was my Platinum SEO Pack. As soon as I deleted the plugin, my Add Media button worked great. Now to figure out another plugin that will do what I need without the same issue.

Richard Cox says:

I had the same issue, I fund that two jQuery files were missing jquery.ui.tabs.min.js and jquery.ui.tooltip.min.js. I found the source in Google Code. they need to be placed in “wp-includes/js/jquery/ui”
