I have over 3000 pages – I want a different main page.

I set up my website using WordPress. The goal, to have about 70 pages directly linked to the main page (my landing page) and most of those pages having anywhere from 5 to 200 blogs coming off each of those.

All seemed well and good until i realized that the reason I was seeing ‘no parent’ as the parent page of each of my 70 pages was because my main page is not a page at all, but merely a blog post!

Oh, no, what to do!

I tried creating an identical page to my initial blog main one. I also went into the settings>reading and checked off that I wanted the main page to land on this new page. I attempted to then begin transferring the 70 pages underneath that newly created page (copy of the original main blog).

But I soon found out that it won’t work, because when I go to the second tier of pages, the url shows three tiers. I want my second tier of pages to have urls that show only two tiers.

this is what i want
https://www.mainpage.com/
https://www.mainpage.com/child-page/
https://www.mainpage.com/child-page/grandchild-page/blog

but instead I have this
https://www.mainblog.com/newlycreatedpage/child-page/grandchild-page/blog

I’m a complete newbie and not familiar with unusual jargon-like web building terms. Is it possible for me to change out the main blog landing site for a main web page, and switch the other child pages over to it so I can have a clean-looking url string?

At this point I am considering trashing over 3000 pages and starting from scratch!
