The Most Common Shopify Bugs and How to Fix Them

Let's be honest. Running a Shopify store is not just about branding and products. It is also about dealing with those why is this not working moments.

The good news is that most Shopify bugs are common, and once you understand them, they are fixable.

Let's break down the ones that show up the most and what to do about them.

SEE THE 7 BUG TYPES

Most bugs are not random. They come from app conflicts, heavy setups, bad edits, or too many moving parts. Once you simplify the system, the store becomes much easier to control.

01. Add-to-Cart Button Not Working

Clicks but Nothing Happens

Customers click and nothing happens.

Common causes include JavaScript errors, app conflicts, and theme customization issues.

How to fix it

Check the browser console for errors.

Disable recently installed apps.

Test with a clean unmodified theme.

03. Broken Layout and Design Issues

When the Store Looks Off

Sections shift, text overlaps, and mobile starts looking questionable.

Common causes are CSS conflicts, app-injected styling, and theme edits gone wrong.

How to fix it

Inspect elements with Dev Tools.

Remove conflicting CSS.

Revert recent theme changes.

05. Apps Breaking Your Store

Install Something, Break Something

You install an app and things start falling apart.

Common causes include poorly built apps, overlapping features, and code injection issues.

How to fix it

Install apps one at a time.

Test immediately after install.

Remove apps cleanly and check leftover code.

07. Mobile Experience Is Broken

Desktop Is Not Enough

The store looks great on desktop but messy on mobile.

Common causes are non-responsive design, app overlays not optimized for mobile, and poor spacing or scaling.

How to fix it

Always test mobile first.

Adjust CSS for responsiveness.

Avoid heavy popups.

02. Slow Website Speed

When the Store Feels Heavy

Your store loads like it is thinking about life.

How to fix it

Compress images without losing quality.

Remove unnecessary apps.

Use lazy loading and lightweight themes.

04. Checkout or Cart Glitches

When Checkout Feels Off

Discounts do not apply, totals look wrong, or checkout behaves strangely.

Common causes include multiple apps modifying checkout, script conflicts, and currency or tax misconfigurations.

How to fix it

Limit cart and checkout apps.

Test checkout step by step.

Verify Shopify settings for tax, currency, and shipping.

06. Random Errors

The Ones That Make No Sense

Things work, then do not, then work again.

Common causes are caching issues, JavaScript errors, and app or theme conflicts.

How to fix it

Test in incognito mode.

Clear cache.

Check the console for hidden errors.

Prevent Bugs

The Smart Way

Keep your tech stack lean and only keep apps that actually drive revenue.

Make changes one at a time: install, test, validate.

Always duplicate your theme before edits.

Do regular cleanup by removing unused code, auditing apps, and optimizing performance.

Think long-term instead of relying on quick fixes.

Final Thought

Bugs Are Not the Problem. Complexity Is.

Bugs are not the real problem. Uncontrolled complexity is.

The more intentional your setup is, the smoother your store runs.

And when your store runs smoothly, you get more conversions, a better user experience, and less stress.
