Configure post pages without columns

Hi. The entries I write are configured automatically with 3 columns. How can you change that configuration to that I was a text of a single block

Hey there

If you are asking to make this 3 column text into 1 column text then you have to take a look at the page/post with on the text mode of the text editor and you should see how these columns are made, you will see a shortcodes of the columns and that’s the thing you have to remove
