Hello (again)
Apologies for a fourth post/question - totally new to wpforo

I am trying to create a privacy policy page for my forum - I originally linked to a post I created but in order to create a facebook API I apparently need it to be a proper page and a forum post.  I created a new page (as I have done on other wp websites) but although the link shows it as https://www.hairdyeforum.com/privacy-policy when I try to preview or post that web address I get a 404 error page.  

I did a search and found this thread from 2017 about a similar issue https://wpforo.com/community/how-to-and-troubleshooting-2/new-page-error-404/ - I dont understand what they mean about creating the page through the forum being wrong - I only have one section in WP for creating pages so am unsure how to create a non-forum parent page (hope that makes sense as had no idea thats what I was doing)

The screenshot shows the page I created but when I click the link I get a 404 error page.  I can only attach one photo at a time on here so will add another post with the error message
