Something broke
Related symptoms worth checking alongside this guide include forms and modals not working and embeds, iframes, and widgets breaking pages because real website problems often cross visual behavior, forms, scripts, tracking, and CMS layers.
If this article describes the symptom on your site, compare Website Fixes and Production Debugging before turning the problem into a request.
If the first fix path is not quite right, Front-End Help may be the better service or skill page. You can also use Contact once you have the URL, symptom, timeline, and what should happen instead.
Common signs
Dropdowns do not open, sliders freeze, modals fail, buttons stop responding, CSS looks different after an update, or console errors appear when the broken feature loads.
Likely causes
JavaScript bugs often come from duplicate libraries, plugin updates, script order, missing dependencies, third-party snippets, minification, cache issues, or code written for an old template.
What to send
Send the page URL, the expected behavior, the broken behavior, recent changes, and screenshots or screen recordings if the bug is interaction-based.
Practical fix path
The first step is usually browser console and network inspection, then isolating the failing script, confirming whether the bug is global or page-specific, and applying the smallest fix that does not break related behavior.
Use the right debugging lane for CSS and JavaScript bugs
Front-end bugs can be visual, functional, script-related, or deployment-related. These pages route the issue based on what is actually failing in the browser.
Website Fixes Use Website Fixes for broken menus, modals, buttons, CSS conflicts, page-specific bugs, and scripts that stop a normal site action.Production Debugging Use Production Debugging when the problem needs console errors, network checks, script isolation, cache review, or production-safe troubleshooting.React & Static Sites Use React & Static Sites when the bug lives in a component, static build, front-end route, JavaScript behavior, or lightweight site deployment.WordPress Support Use WordPress Support when CSS or JavaScript behavior is coming from a WordPress theme, plugin, page builder, shortcode, or injected script.
