Troubleshooting theme issues
There are a few common steps that can help diagnose and pinpoint issues with your theme.
Compare your store to the demo stores
If the issue exists on our demo store then you may have spotted a bug - please notify us and we'll get on to it straight away.
Try different browsers and devices
It's worth trying out different browsers, such as Chrome, Safari, or Firefox. If you're only seeing the issue on one browser then you can upgrade it to the latest version. Browser plugins or extensions can also cause conflicts, so again if it's just the one browser causing the issue, you can try disable these plugins.
Rollback changes or install a fresh copy of the theme
If you edited code in your theme's template files, it's possible your changes could have caused some issues. Try reverting your site using the the code rollback feature or from a backup. We may not be able to support issues resulting in code customizations made by you or third-party developers. If you're unsure about what files were edited, contact your developer to revert any obvious or recent changes to the code.
If you're unsure about what edits have been made, grab a fresh copy of the theme and see if the problem persists on a new install.
Compare with another theme
There are certain functionality limitations to Shopify out-of-the-box which aren't related to themes. You can download Shopify's Brooklyn Theme for free to compare core functionality between themes.
If you've tried all the steps above and are still experiencing the same issue you should try disable any recent Shopify apps or ones you think might be related to the problem. For example, if your issue is occurring on the product page, look for any apps related to the product page such as product reviews, product subscriptions etc.
Note that simply deleting the app from your app dashboard does not always remove code the app has added. You may need to remove references to it added to template files. Contact the app developer or consult the app documentation for full uninstall questions.
If you find that a particular Shopify app was causing the issue it's best to contact the app developer first - they will be more familiar with their code and have probably dealt with this conflict on other themes. We may be able to help diagnose an app conflict, but are unable to support issues with third party apps.
