Search bar not working after enabling Search Config...

Hello,

I have a search bar which has the following code:

print drupal_get_token('search_theme_form'); " />

After enabling the Search Config module, the search using the search bar isn't working anymore. I get redirected to www.XXX.de/search but I have to enter the word again to get a result...

Can you tell me what the Search Config module does to the standard search so that my search bar isn't working anymore? Any suggestions for changing my code on the search bar?

Thank you in advance.

Regards
Florian
