I have a problem when writing a post, before the layout was in 2 columns, one where there is the post box and the other with publish, tag, categories etc… Now is only one column but I don’t like it all! I’ve read on one of the help articles that there should be a Screen layout, number of columns in the screen options but is not there!!! How do I change the settings is order to have back the 2 columns? Thank you!!
