hi, how can i change the number of ad columns on the main page? Thanks

If you mean the home page then please try to edit the home page and here please try to edit the Listings block and change the Columns option

But where I can find it?, how I can do it?

Please open Pages in the WordPress dashboard. Then choose the Home page to edit. Click on the listings block and there will appear a block with settings for the Listing block in the right sidebar Screenshot by Lightshot

As you can see on the screenshot there is a Columns option which is possible to edit to change the number of columns for listing on the home page
