Search isn’t working | WordPress.org

Hello,

i got a problem with the search function.

After setting up everything and starting filling out the database ( with a low privileges user.) Everything was working fine..

but suddenly the search function stops working.

there’s no other plugins. Also i tried the default theme for WordPress. And still the same problem. Search never works.

Can you please help?

I’ll be grateful for your help and support.
