How to resolve the “Do not change the APP PROXY URL” issue in the app editor

While editing in the EComposer editor, it somehow exhibits issues such as the screenshot below. This issue may be related to the theme or your domain. For example, the domain is not connected, not verified,…

To resolve this issue, please choose one of the two options listed.

1. Save the theme in the App settings again

From the App dashboard, open Settings -> Theme Management -> Theme working on -> Click the Save button to save the theme in the app again.

Then open your page again and clear the cache to see if it can solve the issue.

2. Check the Domain for the Online Store

Go to Shopify Settings -> Domains to check your store domain to make sure the primary domain is working fine.

3. Check the APP PROXY URL of EComposer

By default, the app proxy URL is set to ecomposer-visual-page-builder. If you change it, the app may not be able to load and work properly. Please follow the steps below to check and correct it:

Step 1: Go to Shopify Settings -> Apps -> EComposer Builder -> View details

Step 2: Find the App Proxy URL part and click the Customize URL button.

Step 3: Make sure that the handle is ecomposer-visual-page-builder -> Save.

Finally, open the EComposer app again and clear the cache.
