Disabling the top seller


I am trying to disable the top seller from the shop.

I tried to change it from 
Configuration > Cache/perfermance > the Settings Tab > Marketing > Top Seller

But it always throws the message: Internal Server Error.

What may be the caue of this error?
Is there another way to disable it, like template files or something?

Thank you!

Take a look at your Server Error looks from php or apache/nginx and take a look for the error message.

Where do you get the Error Internal Server Error - In the Frontend or Backend? If you get this error message in the frontend, debug the Shopware frontend -> Debugging Shopware

Then you should see the correct error message.

I get the error in the Backend.
Is there a way to debug the Backend as well?

Thank you!

I have the same problem
