Configuration Guides for WordPress

1 guide covers configuration problems in WordPress, from the first symptom to the fix that holds.

Most WordPress breakage traces back to configuration: a wrong constant in wp-config.php, a site URL that does not match the database, or a file permission that worked on the old host and fails on the new one. These guides walk through the settings that actually control how WordPress boots, connects, and writes files, with the exact lines to check and the safe values to restore when something stops responding.
