Javascript error?

[lunacross]

Hi,

I seem to have some Javascript problems since I installed the latest version 1.2.5.0 yesterday:

1. Change currencies on the Front End doesn't seem to work: http://zandras.ethernaut.at/shop/) - a previous install 2 months ago worked...

2. In the back office under > Tools > Translations > Modify translations i see the three flags (german langs pack installed successfully), however when i click on any of the flags (even the french which was pre-installed), nothing happens, the list of fields for editing does not show up anywhere. The bottom left corner of the browser says "Error on page."

I have the same result on IE, Firefox, Chrome and Opera, and the same for my ISP friend who tested it.

Anyone would have a hint what might be wrong (installation / environment variables / permissions)? I have set everything to 777 so permissions shouldn't be a problem.

Many thanks!
