Repository error

Hi,
I am getting an error message with the encoding, when I want to go to the repository/extensions installer.

Any idea what setting could be wrong?
I did transfer the site from local install to a server.

Thanks

Its a 5.4 PHP problem - (not an error on my side ), its on the list of the Contao developers already.

Set the server back to PHP 5.3 and here is my extension repository link running again.
So for now, I should be fine
Thanks!

Good to know, thanks strawberry
