If the URL that you originally entered redirects to another, go back to Mobify Preview at http://preview.mobify.com.
Enter the URL that your original URL redirects to into the "Site URL" form field.
The Preview is Lost on Refresh or on Page Transition
This problem occurs because the cookies and any other local settings are reset during refresh or page transition.
Go back to Mobify Preview at http://preview.mobify.com on your development computer browser.
Use the same settings as when you initialized the preview to reactivate it.
The Preview is Lost After you Open Developer Tools
When you open Developer Tools, the browser changes its user agent. This deactivates the preview.
To resolve this, go back to Mobify Preview at http://preview.mobify.com.
Use the same settings as the ones that you used when you initialized the preview.
Resetting the settings to those initial values reactivates the preview against the new user agent.
Blank Page Appears After Clicking Preview
Check if the page that you are visiting is served on HTTPS.
If it is, click the shield icon in Chrome to accept the security certificate. This is necessary only once per session.
We recommend that you use Chrome for all your Mobify development projects.
