Fixing CPT Slug Conflicts in WordPress Before They Crash Your Site

The 404 Nightmare

Have you ever created a page called "/portfolio" only to realize it's returning a 404 error? That's a slug conflict. Your theme or another plugin registered a Custom Post Type with the exact same slug.

The Instant Fix

You could spend hours digging through functions.php and plugin files. Or you could use the CPTSM Slug Manager. Its interface flags conflicts in red immediately, allowing you to resolve them with one click.
