How to Edit/Route Static Page ISSUES!

[Rfeeks]

Hi all,

I am not familiar with all the coding terms (newbie) but I'm learning! Trying to create a static page on my nodebb site. So I installed the custom static page plugin, created a new button in navigation that should route to the new page, and I'm trying to edit the widget in "Extend Widget". Nothing is working and this page keeps coming up:

Can someone please tell me in simple terms how to edit the custom static page, and route it correctly?? Thanks!
