"Add Media" doesn't work after upgrading to 3.5

Ever hear the tune “One of these things is not like the others“?

Your site’s HTML banner img looks like this:

<img src="https://www.crepealicious.ca/wp-content/themes/twentyeleven/images/headers/lanterns.jpg.pagespeed.ce.j0XxSEz4gH.jpg" width="1000" height="288" alt=""/>

On my Crash Test Dummy running 3.5 and Twenty Eleven I have this.

<img src="https://dixie.dembowski.net/wp-content/themes/twentyeleven/images/headers/trolley.jpg" width="1000" height="288" alt="" />

See that .pagespeed.ce.j0XxSEz4gH.jpg? And on your javascript console you’ve got this too .pagespeed.jm.JRcNp7VG6h.js:60?

Where’s that coming from? My stock 3.5 with just one plugin (Spam Destroyer, love the name) does not include that pagespeed item.

Do you have Google’s mod_pagespeed installed? You can confirm with a simple <?php phpinfo(); ?> file.

i fixed the same issue by following the 101 steps above and identified “Tagaroo” as the plugin that was breaking everything for me. after deactivating it everything was all good. Tagaroo has broken several new upgrades and is on my poo list…

@tkniat: Email me with login information so that I can take a look at your site and see the problem for myself.

You can email me at [email protected].

I’ve just created an admin account for you on https://www.crepealicious.ca.

You should receive an email from the server

Okay, I can see the issue.

The problem you’re having is most definitely related to the mod_pagespeed addon that your server is using. You need to disable that or ask your host to do so, because it is overaggressively modifying the javascript code and script tags, and this is causing the javascript failures and making certain functions of the page not load properly.

In the meantime, you can probably work around the problem by setting the SCRIPT_DEBUG flag to true, but in the long run you’ll need to turn off or disable PageSpeed for the wp-admin section, at minimum.

To enable script debug, you can add this define to your wp-config.php file:
define('SCRIPT_DEBUG', true);

Thank you Otto,

I’ve disabled the PageSpeed in control panel for the entire website and it appears that problem is now fixed.

same issue… Add Media does not work…

does not work in Firefox of IE

works in Twenty Twelve theme…not in Business Pro… Dashboard/Updates says Business Pro is current at 3.1.8 however at CyberChimps the current version is six months newer 3.1.18

added this code to .htaccess … did not solve issue

<IfModule pagespeed_module>
ModPagespeed off
</IfModule>

upgraded theme to BusinessPro 3.1.18 and Add Media now works fine.

CyberChimps site says that their old framework does not work with WP 3.5… new one does

thanks
