Options disappeared after I changed or duplicated my theme

Customei's switch lives inside your theme, not in Customei. Each theme keeps its own settings, so when you publish a different theme, or a new copy of your current one, the new theme may not have Customei turned on. Your option sets and products are fine. The theme just needs to load Customei again.

1. Turn the app embed on in the new theme

1. In your Shopify admin, go to Online Store > Themes.
2. Next to the theme that is now live, click Customize.
3. Open App embeds and turn on Customei Personalized.
4. Click Save. Until you save, the switch does nothing.

You can also start from Customei: click Enable on the Customei app embed is off banner, then click Save in the theme editor that opens. See Turn on the Customei app embed in your theme.

2. Add the Customei block again, if you used one

If you had placed the Customei Personalized block on your product page, add it to the new theme's product template too, then click Save. If you never added a block, skip this step: Customei places the options above Add to cart on its own. See Place the options exactly where you want them.

When Customei still says it's off

• Customei checks your live theme. A theme you're still preparing will read as off until you publish it.
• The check can lag behind the theme editor. If you have turned the switch on and saved, click Check again after a few minutes.

Publishing asks you to turn it on

When you click Publish on an option set and the embed reads as off, Customei opens Turn on the Customei theme helper instead of publishing. Click Enable, click Save in the theme editor, then come back and click Check again. If a check still says off but you know it's on, Publish anyway goes ahead.
