We need an experienced WordPress developer to diagnose and resolve intermittent 404 errors with a custom post type created using Advanced Custom Fields (ACF).
# Problem
Custom post type returns 404 errors under specific conditions:
– After adding a 301 redirect in RankMath SEO
– After visiting the Permalinks settings page (no changes or save required)
**Temporary fix:** Visiting the ACF taxonomy page for the CPT and saving (no changes) resolves the 404 until the next trigger.
This indicates a permalink/rewrite rule issue, likely a simple misconfiguration.
# What We Provide
– Admin access to a configured dev environment
– Pre-configured staging environment for testing resets
– Full site context and documentation
# Deliverables
1. Root cause identification
2. Permanent fix implementation
3. Edge case testing (redirects, permalink changes, ACF updates)
4. Technical documentation detailing:
— Root cause
— Solution implemented
— Prevention steps for future configurations
# Timeline
– Solution: 48 hours from contract acceptance
– Documentation: 24 hours after solution approval
