1. A new shortcode function exists but WordPress prints the tag literally. What should you inspect first?

A new shortcode function exists but WordPress prints the tag literally. What should you inspect first? Child-theme colors Whether its PHP file is required by includes/shortcodes/load.php and the tag is registered Updater backups SEO schemas

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
2. A shortcode works directly but is absent from a managed page. What integration is most likely missing?

A shortcode works directly but is absent from a managed page. What integration is most likely missing? Its GitHub release ZIP Its Shortcode Manager declaration/configuration for that entity and layout The parent theme screenshot Its database password

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
3. A shortcode returns correct HTML but looks unstyled only on one page family. What should be traced?

A shortcode returns correct HTML but looks unstyled only on one page family. What should be traced? CPT rewrite flushing only Database collation Remote HMAC timestamps Addon CSS registration plus the active child template package and its declared assets

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
4. Content appears, but the header and layout differ from sibling pages. What is a likely cause?

Content appears, but the header and layout differ from sibling pages. What is a likely cause? The shortcode query has too many posts The taxonomy is non-hierarchical The root template bypasses the expected child-theme shell or selects a different package The updater nonce expired

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
5. The same script executes twice after a customization. What should be checked?

The same script executes twice after a customization. What should be checked? GitHub availability Duplicate enqueue paths across the partial, addon hook, and child package Only the database post count REST authentication

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
6. A newly registered public CPT works in admin but single URLs return 404. What is the best first sequence?

A newly registered public CPT works in admin but single URLs return 404. What is the best first sequence? Move the CPT to the child theme Confirm registration/rewrite settings, flush permalinks once, then trace single-template resolution Delete all posts Disable every plugin

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
7. A metabox renders but values never persist. Which path must be audited?

A metabox renders but values never persist. Which path must be audited? GitHub tag comparison save_post hook, nonce, autosave/revision guards, capability, sanitization, and correct meta key Shortcode output buffering only Footer CSS and fonts

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
8. An AJAX filter returns zero results although posts exist. What should be compared?

An AJAX filter returns zero results although posts exist. What should be compared? Submitted sanitized filters, taxonomy/meta query construction, post status, and response handling Updater storage size Only the child-theme logo Translation catalog headers

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
9. A private question CPT must never expose correct answers. What is the sound design?

A private question CPT must never expose correct answers. What is the sound design? Keep public exposure restricted and calculate correctness from server-side data Hide answers with CSS Trust a browser flag Send answers in JSON but obfuscate keys

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
10. A child override exists but the addon template still renders. What should you establish?

A child override exists but the addon template still renders. What should you establish? Whether WordPress cron ran The active resolver precedence, expected override path, active child package, and exact filename The updater secret length The number of admin users

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
11. A support plugin silently uses defaults instead of site rules. What should be verified?

A support plugin silently uses defaults instead of site rules. What should be verified? CPT permalink pagination Config path, JSON validity, schema/keys, active child theme, and fallback diagnostics Remote ZIP extraction Parent theme screenshot

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
12. English strings remain untranslated despite a PO file. What should be checked?

English strings remain untranslated despite a PO file. What should be checked? HMAC body ordering Only the permalink structure Exact text domain, domain loading, source string extraction, compiled MO, and locale Backup retention

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
13. A feature passes locally but fails live. What comparison should lead the diagnosis?

A feature passes locally but fails live. What comparison should lead the diagnosis? Assume deployment succeeded Immediate core rewrite Versions, active packages, configuration, PHP/runtime environment, logs, and actual response evidence Only screen width

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
14. A fleet batch reports one failed package among several successes. What is the correct state model?

A fleet batch reports one failed package among several successes. What is the correct state model? Unknown until the local theme changes A partial result requiring per-package and per-site verification, not an atomic fleet rollback Total failure with guaranteed automatic rollback Total success because most packages passed

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
15. A scaffolded addon contains labels from its model addon. What should happen?

A scaffolded addon contains labels from its model addon. What should happen? Review and replace residual domain references while preserving the generated structure Ignore them because generation proves correctness Create another parallel bootstrap Move all files into the core plugin

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
16. An archive becomes slow after adding meta filters. What evidence should you gather?

An archive becomes slow after adding meta filters. What evidence should you gather? Only CSS file sizes Updater nonce transients Translation locale Query arguments, SQL/query monitor output, result counts, indexes/cache behavior, and pagination

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
17. A public action has a nonce but no authorization check for privileged changes. Is it secure?

A public action has a nonce but no authorization check for privileged changes. Is it secure? Yes; a nonce grants administrator rights Yes if JavaScript hides the button No only when HTTPS is disabled No; intent verification does not replace capability or ownership authorization

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
18. Why escape values in the final rendering context even after sanitizing on save?

Why escape values in the final rendering context even after sanitizing on save? Escaping improves database indexes It registers the shortcode It validates GitHub releases Storage normalization and output-context protection solve different problems

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
19. What is the strongest general Lubinik debugging order?

What is the strongest general Lubinik debugging order? Clear all data before reading logs Copy every template into the child theme first Modify core and parent together Identify context, trace the active loader/hook/resolver, inspect inputs and outputs, isolate ownership, then change the smallest responsible layer

Hint
Trace ownership and runtime flow before choosing the smallest responsible change.
20. How should you explain a completed Lubinik feature in an interview?

How should you explain a completed Lubinik feature in an interview? Claim production proof from a local lint Describe only the final CSS List filenames without explaining interactions State ownership, request/render flow, security decisions, extension points, tests, and known boundaries

Hint
