Posts not sequential

Hi,

Could someone tell me how I can get my posts in sequence?

This was not a problem before I switched of the slider on the home page. After I switched off the slider the sequense of my post turned. It was from newest to oldest, but now it is from oldest to newest.

I can’t figure out what I did wrong. Maybe I need to checkmark something or not, or I need to change my post options.

Thanks
