Product pages not working with multiple languages

[Spotted Projects]

Hi All

 

I've made an upgrade from 1.4.9 to 1.5.0.17. Everything went fine. All the URL's are working for Dutch, which is the default language.

When I switch to the second language, French, the URL's are ok but I get an empty page. Nothing is loaded. The page stays blank.

In the old version 1.4.9 everything was ok.

 

Somebody who knows what the problem is?

 

I use the default theme.

 

Thanks a lot!

Robin
