Core Check Guide

Core CheckExplained

Core Check verifies WordPress core integrity by comparing installed core files against expected WordPress checksums. It helps support teams quickly identify modified, missing, or unexpected core files so repair decisions can focus on the WordPress installation itself instead of unrelated wp-content files.

Checksums

Modified
Find core files that changed.
Missing
Spot expected core files that are gone.
Unexpected
Review files that should not be in core.

Verify the WordPress core installation

Core Check focuses on WordPress core files. It keeps the review centered on the files WordPress itself expects so modified, missing, or unexpected core files are easier to separate from plugins, themes, uploads, and custom site content.

Checksum Comparison

What it means: The check compares installed WordPress core files against expected checksum data for the WordPress version in use.

How to use it: Run it when core tampering is suspected or after a cleanup to confirm the installation is clean.

Modified Core Files

What it means: Modified results point to core files whose contents differ from what WordPress expects.

How to use it: Replace modified core files with clean copies when the change is not intentional or cannot be explained.

Missing Or Unexpected

What it means: Missing files can break WordPress behavior, while unexpected files inside core paths may deserve immediate review.

How to use it: Treat missing and unexpected results as focused repair tasks, then retest after correction.

Clean Retest

What it means: The strongest confirmation is a clean follow-up check after repairs are complete.

How to use it: Retest after replacing files so the report confirms that core integrity has been restored.

Important: Core Check is focused on WordPress core. Review wp-content files with the auditor, scanner, or file change tools instead.
