"undefined $" - jQuery errors #1497

Hallo ,
i've recently updated from piwik 6.3 .
I've noticed that can be a problem for the index , with jQuery errors on "undefined $" that point to lines where are present options with international characters , for example thai .

The configuration of my webserver is to output as default "UTF-8" encoding , so the Asian, arabin characters are writtend the rights way , but european character like ( german, spanish, portoguese ) was replaced by html encoding "à" and so on .
Very strange for an utf-8 page . In the error log nothing appears , so IMHO the problem is just on client-side . I've tried with :
Firefox : 3.6.6 Ubuntu 10.4
Firefox : 2.0.0 Ubuntu 7.10
Chromium : 5.0.375.99 (51029) Ubuntu 10.04
( sorry i don't use finestral(o)s )

To bypass : Deactivate LanguagesManager, and the reactivate it .

Keywords: jquery,language,missing output,index,sites


We expect mbstring.func_overload = 0.

Can you check your php.ini or phpinfo(), and tell us if mbstring.func_overload is non-zero?


Can you check the permissions on the tmp/assets folder (and its contents)? The folder needs to be writeable by the web server user, and obviously be able to read/write/update/delete files in that folder.

(Are merged assets not regenerated when the language is changed?)


yes all directories are writable .
i've restored simply disable and reanble the LanguagesManger .
Now it's ok .

(Are merged assets not regenerated when the language is changed?)
i've not changed the language , it happened automaticly after upgrade .
I think is a DB issue , because i've tried also new installation on an upgraded DB .

(Are merged assets not regenerated when the language is changed?)
I don't think they should be deleted.. should they?

matteocisilino, it is maybe just a problem with a UI string missing encoding. What Piwik language were you using?

were you using SVN version before updating, or simply upgraded from the previous 0.6.3 version?


Attachment: empty dashboard with javascript errors


Attachment: same result with LanguagesManager disabled


same error for us, we did an upgrade from 0.5.4 to 0.6.4.

If we logon to the backend as admin-user, the website is rendered, but the dashboard is empty. We get the following javascript errors as outlined in the screenshots.

We already deleted the tmp folder, permissions for tmp/* is 777.
Apache is not configured for UTF-8.
mbstring.func_overload = 0

can you please send your piwik URL in anonymous here, or send by email login+pwd? I'd like to see the error


Sure, where should I sent the login+pwd?

Hello all,
please send your login + pwd + piwik URL to matt attt piwik.org thanks!


Hi there,

I am having the same issue and and I found a temporary solution:
The javascript files were packed in the wrong order.

I edited tmp/assets/<long number>.js and moved the part with the jQuery library to the beginning of the file - before all jQuery plugins. Shift reload in the browser then made the tab contents load.

I'm not sure how the packaging of the js is implemented, however it should ensure the correct order of the js files.

Maybe this helps fixing the bug.


In my case , the js is packed in the right way .

  • jQuery JavaScript Library v1.4.2 and then /*!
  • jQuery UI 1.8.2

I still viewing strange things .
now the dashboard is white , with the ajax response that isn't rendered , but as before the code is ready in the browser.

(In [2637]) Fixes #1497 Hopefully fixing this one by forcing jquery.js, jquery-ui.js etc. to be first in the list therefore in the generated merged JS.

Please try the patch and report if it works for you. thx!

Pleas replace your piwik/core/AssetManager.php file by this new one: https://github.com/piwik/piwik/blob/master/core/AssetManager.php?rev=2638&format=txt and let us know if it fixes the issue as expected.

Piwik Open Source Analytics member

Note: please delete tmp/assets/* to force the js to be regenerated.


I can confirm that I do not experience the issue anymore after replacing core/AssetManager with your new version with the ensureJsFilesSorted() method. Thanks a lot for the quick fix.


I can also confirm that the replaced file fixes the problem. Thanks a lot, awesome.
(using php 5.2.10)


Does it still work if you replace:

    return array_unique($jsFiles);


    return array_flip(array_flip($jsFiles));

In the patched core/AssetManager.php file? In which line? I cant find "return array_unique($jsFiles);"



@vipsoft Unfortunately it doesn't in my installation. Same Javascript errors (jQuery and $ not defined).

This is what I tried:

        private static function getJsFiles()
                Piwik_PostEvent(self::JS_IMPORT_EVENT, $jsFiles);
                return array_flip(array_flip($jsFiles));


It doesn't , i'm using php : PHP 5.2.0-8

Piwik Open Source Analytics member

Is there anyone still having issues with this,

  • with the new AssetManager.php file,
  • after deleting tmp/assets/*

anyone still with a JS error?


Ok. It makes sense that it doesn't work with array_flip ... the order that plugin hooks are called by PostEvent isn't guaranteed to be in a particular order.

I do have this issue after moving my Piwik to an new VPS.
My luck: the old VPS will be running piwik for one week from now.

So the DB is on the new VPS and is running fine. The Piwik is on the old and the new VPS, but on the new one its not running in this case.

Can anyone give me support, I have made all of the given tipps here ^^

Tanks all,

PS here's the console from overall-dashboard:
Uncaught SyntaxError: Unexpected token < /index.php?module=Proxy&action=getJs&cb=97b6d5efe49e97d4303feb7993750b30

Uncaught ReferenceError: prepareRows is not defined index.php?module=MultiSites&action=index&idSite=1&period=day&date=today

Here from single Page

Uncaught ReferenceError: $ is not defined index.php?module=CoreHome&action=index&idSite=1&period=day&date=today


Sorry for reopening, wasn't as hard as it seems...

Just -as admin- go to "Settings > System Check" and have a look to the output.

In my Case it was the non-binary-upload...

  1. Backed up global.ini.php
  2. Re-Downloaded Piwik
  3. Deleted Piwik from WebSpace
  4. Uploaded the fresh Piwik
  5. Uploaded the (in step 1 back-uped) global.ini.php
  6. Visit Piwik-Instance-URL and have fun :)

I'm sorry to say this, but I'm having exactly this old problem once again in 2.12.1, after an upgrade from 2.8.3. When loading the Piwik dashboard, I get these errors:

ReferenceError: $ is not defined index.php:68:8
ReferenceError: $ is not defined index.php:753:0
ReferenceError: $ is not defined index.php:778:0

So jQuery seems not to be loading. Moreover, there actually appear to be no network requests on the page except for the initial GET request.

I've attempted forcing tmp/assets to regenerate, but no luck.

Hi @PabloCastellano please create a new issue with your error message (and screenshot) as this one is closed


Hi @mattab i am getting ReferenceError: $ is not defined

Due to this my dashboard is empty .Please help.

Piwik Open Source Analytics member

Maybe your JavaScript can't be loaded. Are there any loading errors (404/500/...)?


In my case it was the ublock extension (similar to adblock) which was blocking javascripts. Can you check it too @sandeepjain2015?

Piwik Open Source Analytics member

when you have ublock extension enabled, do you see a message in red, that asks you to try disable the ad blocker extension? We added this in #10137 so hopefully you can see it
