Hi,
I'm new to Grav, and I'm having major issues troubleshooting it.
The client made the following changes on their website:
- Duplicated a page. This was (I believe) a listing page, since it contains multiple news article items.
- made edits on the duplicated page.
- deleted the original page.
The news article items are visible but the parent /news/ page is not found and it keeps refreshing infinitely.
Console log screenshot:

user/themes/m2/en/home DOES NOT exist on the server.
user/themes/m2/home DOES exist on the server.
I'm NOT receiving Grav Error 404 Page. The preloader never stops loading and then the page keeps refreshing infinitely.
I know this is a looong stretch and I apologize if I'm being unreasonable asking for directions.
Many thanks in advance.
