Thanks Juliette,
So I've added the error code to my wp-config on the staging server:
http://acquireb2bdev.com/resources/data-sheets
The staging site currently shows the incorrect view on those pages by not showing the page content and the pages are being rendered as blog listing pages.
The error code is not creating a file to share with you so I must have some setting wrong (I created a logs directory with 777 rights but no file gets created in there - I didn't modify the .htaccess file - is that really necessary?) but you can go to the page(s) and see all of our beautiful warnings etc.
Could you take a look and see if you can detect why this is happening?
I really appreciate your time.
Chris
