CSS and JavaScript Issues in WordPress
Frontend issues — broken layouts, scripts not loading, mobile display problems — account for a large portion of my WordPress support work.

Really helpful guide! Solved my issue quickly.
Glad it worked for you!
The section about JavaScript conflicts in WordPress is spot on. I had a case where a theme was loading jQuery in the footer while a plugin expected it in the header. Took me forever to figure out it was a loading order issue. Your debugging approach with the browser console would have helped a lot.
Loading order conflicts are one of the most common JS issues in WordPress! A quick diagnostic trick: open DevTools → Console, and look for ‘undefined’ errors — they almost always point to a dependency loading too late. Using wp_enqueue_script with proper dependencies array prevents most of these.
