The "404 Not Found" Nightmare: Diagnostic and Repair
There is nothing more frustrating than clicking a link in your WordPress menu and seeing a 404 error—especially when you know the content exists. In WordPress, 90% of CPT-related 404 errors are caused by rewrite rule conflicts.
The Hidden Cause of Slug Conflicts
* Duplicate Bases: Two plugins using the same slug (e.g., both using "events"). * Page vs. CPT: You have a top-level Page named "Services" and a CPT also using the slug "services." * Stale Permalinks: You changed a slug in code but didn't "flush" the rules.How Melopo CPTSM Slug Manager Fixes This
Instead of digging through yourfunctions.php or database, CPTSM provides a Real-time Conflict Detector.
Visual Warnings: If a slug you're trying to set is already in use by another CPT or Page, the plugin will warn you before* you save.
