I have looked everywhere in the forum for this, but in vain.
I am trying to insert a nextpage tag into the html view of my post. Every time that I do it, I go back to the edit view and see an extra line in the text.
Returning to the HTML view, I find that the tag has disappeared.
I have used <!-nextpage-> as given in the pagination guide, and also <!nextpage> as someone mentioned elsewhere in the forum, but neither work.
Any idea why this happens and how to remedy the situation? I have wasted enough time on the problem and would just like to go back to concentrating on the content of the post.
