PROBLEM SOLVED

Root Cause

The Apus Theme was generating custom Schema.org JSON-LD markup while Rank Math was generating its own, causing:

• Duplicate schema items in Google Search Console
• Conflicting structured data
• Potential ranking confusion
• Invalid rich results warnings

Solution

Priority 1 Hook Filter - Disables Rank Math's schema output while preserving the theme's comprehensive schema implementation:

function apus_disable_rankmath_schema() {
    if (class_exists('RankMath')) {
        add_filter('rank_math/json_ld', '__return_false');
    }
}
add_action('wp_head', 'apus_disable_rankmath_schema', 1);

Result: Single, unified schema output from Apus Theme

---

SCHEMA COVERAGE

The theme now generates all necessary schemas without duplication:

1. Organization - Company information
2. WebSite - Site structure with search integration
3. Article - Blog post metadata
4. WebPage - Static page information
5. BreadcrumbList - Navigation path for all content types
6. HowTo - Process-based content (Issue #42)
7. FAQPage - Automatic FAQ detection (Issue #38)

All output as valid JSON-LD in a single @graph structure.

---

RANK MATH COMPATIBILITY

What's Disabled

• Rank Math's automatic JSON-LD schema generation
• Yoast SEO's JSON-LD output (as fallback)

What's Preserved

• Rank Math's Meta Tags (title, description, keywords)
• Rank Math's Sitemap generation
• Rank Math's SEO Analysis features
• Rank Math's Admin Interface

Detection Method

Two-layer detection ensures proper handling:

1. class_exists('RankMath') - Class presence check
2. defined('RANK_MATH_VERSION') - Version constant check

---

TECHNICAL IMPLEMENTATION

Files Modified

Primary File: wp-content/themes/apus-theme/inc/schema-org.php

• Lines 622-633: New apus_disable_rankmath_schema() function
• Lines 26-75: Main schema output function (already present)

Integration File: wp-content/themes/apus-theme/inc/seo.php

• Lines 138-140: Rank Math detection function
• Lines 150-173: Fallback schema for non-Rank Math installs

Master File: wp-content/themes/apus-theme/functions.php

• Lines 195-197: Loads schema-org.php
• Lines 189-192: Loads seo.php
• Both include statements properly protected with file_exists() checks

Hook Priorities

WordPress wp_head action flow:
├── Priority 1  : apus_disable_rankmath_schema() [FILTER PLUGINS]
├── Priority 5  : apus_output_schema_jsonld() [OUTPUT THEME SCHEMA]
├── Priority 10 : Default WordPress hooks
└── Priority 20+: Other theme/plugin hooks

CONTACT & SUPPORT

In Case of Issues (Post-Deployment):

Minor Issue (No Schema Output):

• Check: Is Rank Math installed?
• Check: Is schema-org.php included in functions.php?
• Solution: Clear cache and reload page

Plugin Conflict:

• Check: /wp-content/debug.log for PHP errors
• Review: Plugin activation order
• Fallback: Rank Math filter should handle Yoast too

Performance Issue:

• Expected: No performance impact from this hotfix
• Monitor: Debug.log and error messages
• Check: No other theme modifications made simultaneously

Rollback Procedure (If Needed)

1. Comment out lines 622-633 in schema-org.php
2. Or: Revert entire theme from backup (1.7MB)
3. Time to rollback: < 5 minutes
4. Zero downtime possible

---

NEXT STEPS

1. Immediate: Deploy to staging
2. Within 1 hour: Verify Google Search Console
3. Within 24 hours: Run Rich Results Test
