Can you test with debug mode at 2 ? I'm sure it's a js Compress issue .

And see at your js console if there are a error (and send it here)

I have the same problem. After switching debug to 2 I get in the console:

SyntaxError: missing ; before statement
ext-searchbox.js (wiersz 2, kolumna 7)
TypeError: t is null
c_f4b23...2096.js (wiersz 749, kolumna 191981)

wiersz=row, kolumna=column

Then not js compress issue .... i can not reproduce , with FireFox 41.0.2 and last version.

Now I see that in fact I didn't switch debug to 2. I tried again and I got hundreds lines of code. Most of them are repeated:

Strict Standards: Only variables should be passed by reference in /var/www/clients/client213/web577/web/framework/i18n/gettext/CGettextMoFile.php on line 76 Strict Standards: Only variables should be passed by reference in /var/www/clients/client213/web577/web/framework/i18n/gettext/CGettextMoFile.php on line 234 ....

And then:

You PḦP version (set debug to 0 to go to PHPinfo).

ANd actually : with debug=0 , try adding :
'clientScript'=>array(
'combineJs'=>false,
'compressJs'=>false,
),

At same level than
'urlManager' => array(
......
),

Confirm the issue :

'urlManager' => array(

...............
),
'clientScript'=>array(
'combineJs'=>true,
'compressJs'=>false,
'excludeFiles'=>array(
'/third_party/ace/ace.js',
),
),
),
// Use the following config variable to set modified optional settings copied from config-defaults.php
'config'=>array(

Fix the issue ....

After adding the code to config.php the search option works.

For debug error : Forum post : https://www.limesurvey.org/en/forum/installation-a-update-issues/102774-upgrade-failed-and-replacing-previous-install-failing-too#127614

I'm not sure if it's PHP version or if we need to fix this.

Not an easy fix. We will need to replace the ExtendedClient extensions with a better one.

J'ai le même problème. Je suis en PHP Version 5.3.3 avec une base PostgreSQL 8.4.20.
J'ai suivi la procédure de Denis Chenu mais les boutons Find et Replace ne fonctionnent pas alors que Undo et Redo fonctionnent correctement !

I have the same problem. I am in PHP Version 5.3.3 with 4.8.20 PostgreSQL database.
I followed the procedure by Denis Chenu but the Find and Replace buttons will not work as Undo and Redo work properly!

@c_schmitz : yes , and same for map.js.

Quick fix is update https://github.com/LimeSurvey/LimeSurvey/blob/master/application/config/internal.php#L42 (excludeFiles) in internal.php BUT : if user protect non assets url : broken.

@fabrob11 : 'combineJs'=>false, fix the issue. If you have another error : please copy/paste the javascript error log .....

Fix committed to master branch: http://bugs.limesurvey.org/plugin.php?page=Source/view&id=16380
