How to Fix Squarespace Code Injection Breaking On Mobile

Follow these steps in order. Most Squarespace users resolve this issue within the first 3 steps.

01

Check Your Browser

Clear your browser cache and cookies, then reload the page. Try opening your site in an incognito/private window to rule out browser extensions or cached data causing the issue with code injection.

02

Inspect in Squarespace Editor

Log into your Squarespace dashboard, navigate to the affected page, and check the settings for code injection. Make sure all fields are filled correctly and no options are misconfigured.

03

Review Recent Changes

If code injection was working before, think about what changed recently. Did you add custom code, switch templates, update plugins, or change any settings? Undo recent changes one at a time to isolate the issue.

04

Check Device & Responsiveness

Test your site on multiple devices (phone, tablet, desktop) and browsers (Chrome, Safari, Firefox, Edge). The issue with code injection breaking on mobile may only occur in specific environments.

05

Examine Custom Code

If you've added any custom CSS or code injection, temporarily remove it and test again. Custom code is the #1 cause of code injection issues on Squarespace — a syntax error or specificity conflict can break things.

06

Review Squarespace Status

Check status.squarespace.com to see if there's a known platform issue affecting code injection. Squarespace occasionally has service disruptions that can cause temporary problems.

07

Contact Squarespace Support

If the built-in fixes don't resolve code injection breaking on mobile, contact Squarespace support with screenshots, your site URL, and a description of the issue. They can check server-side settings.
