WordPress Case Studies & Practical Application 2

Question 1

A client's WooCommerce store is experiencing slow checkout pages. After investigation, you find that 12 payment gateway plugins are active but only 2 are used. What is the best first step?

Accepted Answer

Deactivate unused payment gateway plugins

Answer

Deactivating unused plugins reduces PHP execution overhead and database queries on every page load.

Question 2

A membership site built on WordPress shows that logged-in users see cached pages meant for guests, exposing private content. What is the root cause?

Accepted Answer

The caching plugin is not excluding logged-in users from the cache

Answer

Most caching plugins must be configured to bypass cache for authenticated users to prevent serving wrong content.

Question 3

You are migrating a WordPress site from HTTP to HTTPS. After updating the Site URL and Home URL, internal images still load over HTTP. What tool best fixes this in bulk?

Accepted Answer

Use the Better Search Replace plugin to update URLs in the database

Answer

Better Search Replace performs a serialization-safe find-and-replace across all database tables to update HTTP references to HTTPS.

Question 4

A WordPress multisite network's sub-site suddenly returns a 404 for all pages after the main site was moved to a new domain. What is the most likely fix?

Accepted Answer

Update the domain mapping in the wp_blogs table and network settings

Answer

Multisite stores domain and path information in wp_blogs and wp_site tables that must reflect the new domain.

Question 5

A news site's WordPress editor complains that the Gutenberg block editor is too slow when editing long articles. Which approach has the least risk and most immediate impact?

Accepted Answer

Disable all third-party Gutenberg block plugins not needed for that post type

Answer

Each additional block plugin registers scripts that load in the editor, so removing unused ones directly reduces editor load time.
