Magento CE 1.9.0.0 downloadable product does not open uploader

Question

In Magento CE 1.9.0.0 I have the problem that when I add a downloadable product in backend and want to add the file by clicking "Add new row" nothing happens.

The console reports:

SyntaxError: unterminated string literal 'Dieser Inhalt erfordert die neueste Version des Adobe Flash

Does someone know in which file the error occurs?

Answer 1

After searching for the answer I came across a hint that was the solution. The Problem is probably caused by a language file:

Answer 2

The file uploader uses flash, please make sure you have an up to date version of flash installed for your browser.

Answer 3

The root cause for this problem is the file app/locale/de_DE/Mage_Media.csv which somehow contains an additional line break at the end of the file:

"This content requires last version of Adobe Flash Player. Get Flash","Dieser Inhalt erfordert die neueste Version des Adobe Flash Players. Flash herunterladen 
"

Of course this can easily be fixed by removing additional line break or adding a translate.csv to your admin theme and adding the line

"Mage_Media::This content requires last version of Adobe Flash Player. Get Flash","Dieser Inhalt erfordert die neueste Version des Adobe Flash Players. Flash herunterladen"
