I have 20 years experience developing LAMP apps, but I'm new to Expression Engine. I'm helping someone edit a site that was abandoned by the developer.
The site uses EE2 with the Structure module. They had a parent-level item that displayed listings. When I make it a sub-menu item to another parent-level item, the listings disappear. It says no listings found, even though I created a channel associated to that listing category.
Also, I see a lot of help being offered to use this or that code, but I can't tell where the template is that governs the layout of that page.
Can someone point me in the right direction to understanding this?
