Hey - thanks for the response. I've had to learn a bit about putty and bash, but here's my findings so far:
I can create new pages which work well. The perms on the imported pages is 755. Perms on newly created is 644.
I tired to discern ownership of the pages through SSH. Weirdly, I cannot see the page files for the imported ones, but I can see newly created ones. They're just not visible in console. They are visible in CPanel File Explorer.
I read here that owner of data and conf should commonly be "www-data" and to use "ps -ef" to find out what it should be. I did this, and the result was my cpanel username, not www-data, and these folders are owned by my cpanel username...
Not sure what to look for in terms of case sensitivity and naming conventions..
