# BUG-004D — Runtime DOM Investigation & Missing Icon Root Cause Analysis

Act as a Senior Frontend Engineer, PHP Engineer, and Browser Debugging Specialist.

IMPORTANT

This is NOT a feature release.

This is NOT a redesign.

This is NOT another Font Awesome migration.

Font Awesome has already been migrated multiple times.

However, the browser still does not display several icons.

Your task is to find the ROOT CAUSE.

==================================================
PROBLEM
==================================================

The browser still shows missing icons.

Examples:

- Couple sidebar icons missing.
- Login user icon missing.
- Login password icon missing.
- Some action icons are still missing.

Previous walkthroughs claimed the migration was complete, but the browser proves otherwise.

The browser is the source of truth.

==================================================
DO NOT
==================================================

Do NOT blindly replace icons.

Do NOT rewrite layouts.

Do NOT migrate SVG again.

Do NOT modify colors.

Do NOT redesign.

==================================================
STEP 1
Identify the Render Path
==================================================

For every missing icon:

Determine exactly which PHP file renders it.

Example:

Login

↓

Layout

↓

Component

↓

HTML

↓

Browser

Show the complete rendering chain.

==================================================
STEP 2
Inspect Generated HTML
==================================================

Open browser.

Inspect Element.

Verify whether the rendered HTML actually contains

<i class="fa-...">

or not.

If the tag does not exist,

find which PHP file removed it.

If the tag exists,

investigate why it is invisible.

==================================================
STEP 3
Determine Root Cause
==================================================

Possible causes include:

Wrong include()

Wrong layout

Conditional rendering

Permission checks

Old component still used

Wrong icon class

Missing CSS

Font family override

Display:none

Pseudo element conflict

Tailwind purge

Template cache

Any other runtime issue

Do NOT guess.

Prove the cause.

==================================================
STEP 4
Fix ONLY the Root Cause
==================================================

After identifying the exact cause,

fix ONLY that cause.

Avoid unrelated changes.

==================================================
STEP 5
Browser Verification
==================================================

Verify visually:

✓ Password icon

✓ Eye icon

Couple Login

✓ User icon

1. Root Cause Analysis
