nobody knows or even have a hint?

hi there

i have a strange problem an i even didnt got a hint in the web.

I have a joomla 1.5.15 site with joomfish V2.0.4 and virtuemart 1.1.4 stable .

that worked perfect. then i decided to test a sef tool to optimize the hole thing.

i took joomsef 3.6.4. then i got the problem that in vm, even i didnt use sef for vm, the modules and the static text where not translatet in the other languages. it's just english and stay english. but my default language is german.

Even i uninstall joomsef the problem is still there. i dont know what i should do now :(

So i am asking for some assistance here, pleas.
