How many times the problem you’ve faced was caused by ….. wrong configuration:
- Environment-specific – TEST/UAT/PROD config is enabled in wrong environment

When to blame config?
Configuration is worth inspecting as soon as you hear:

How to view Sitecore config?
Sitecore configuration file is built during system startup and cached inside
Sitecore.Configuration.ConfigReader.config
(newer)Sitecore.Configuration.Factory.configuration
(old versions):

XmlDocument is NOT stored as plain text, hence should be assembled back into human-readable format somehow.
Kudos to NetExt extension for saving the day:

!wxml
restores XML:

Only Sitecore
configuration node is stored there, while native config parts could be read via !wconfig

Alternative approaches
Showconfig tool
One could use SIM Tool, showconfig to re-build configs from web.config + App_Config copy. Are there any guarantees it uses exactly same algorithm as the Sitecore version you are using does?

Showconfig admin page
Requesting sitecore/admin/showconfig.aspx
from live instance – the most trustworthy approach. However CDs have that disabled for security reasons, so not an option.
Support package admin page
Support Package
admin page would ask all servers online to generate their configs:
