Using protocol-independent URLs
Different web protocols might cause your store to behave unexpectedly for some users.
- Colors do not display correctly
- Some page elements or images do not appear
Your browser address bar shows a warning:
This might happen if some of your theme assets do not use protocol-independent URLs. These URLs are required if you want to load your site through a secure connection (
URL protocols look like
ftp://. A protocol-independent URL simply begins with
You might be loading your store through a secured connection (
https) if any of the following apply to you:
- you use the
.myshopify.comaddress as your primary domain
- you're a Shopify Plus merchant with custom SSL security on your store
- you've activated SSL for your online store.
For your store to load properly, all theme assets must use your store's secure protocol. You can make sure this by replacing the
http:// in their reference addresses with
Updating assets to use protocol-independent URLs
To make sure your assets work properly when when your store is viewed through a secure connection, search your theme files for the text
http://, and replace all instances of that text with
//. For example:
<link href='http://fonts.googleapis.com/css?family=Open+Sans' rel='stylesheet' type='text/css'>
<link href='//fonts.googleapis.com/css?family=Open+Sans' rel='stylesheet' type='text/css'>
You can export your theme and use the Replace all feature in a text editor to replace the URL protocol in all your theme files. You can then import your edited theme, and publish the imported theme that has protocol-independent URLs.
To find out which assets are not loading securely, you can check your browser console. The console should list the assets that are not loading properly.
You might notice that YouTube videos don't load in the online code editor. This is because the embed code for these videos doesn't use the HTTPS protocol. Not to worry though, they'll still display properly on your online store.
