admin panel- error

[alitwitz]

Hello,

The panel did not register any variation. 

 

For example I can`t disable cache

It has nothing to do, there are some errors.

 

Any ideas?

 

Cheers

Are you using multistore?
This usually happens when there are duplicate entries for those configurations in the database. you can also check for that

Unfortunately i am using single store.

 

I wrote to my hosting but they said everything ok. Maybe i should reinstall presta and install my database?

I don't think it's necessary, you can just get rid of the duplicates if they are in the database (you can check through phpmyadmin)
