I added <!–nextpage–> and the buttons with numbers 1 and 2 appear at the bottom of the first page. But if I click to the second page, there are no buttons at the bottom of this page so i can not return easily to the first page. If I put <!–nextpage–> again, there will appear three buttons, but the third one i don’t need. Is there a plugin for previous or something? I would like to see 1, 2 at the first page and 1, 2 at the second. Can somebody help me please?
